King Cobra Shaker Rubber Strip: Replacement, Sizing, and Compatibility Guide
To replace a King Cobra shaker rubber strip, first confirm where it fits in the screen assembly, then compare the old strip or its drawing with the replacement across profile, width, thickness, length, and mounting details. Do not rely on the “King Cobra” name alone: equipment configurations and replacement-part dimensions can vary, and a strip that looks similar may not seat or seal correctly. At Yuanpeng, we recommend sending clear measurements, photographs, and the shaker or screen details to your supplier before placing an order. This guide explains what to check, how to measure, and what information helps a B2B supplier assess compatibility.
Key Takeaways
- Match the rubber strip to its specific position and function in the shaker or screen assembly.
- Compare the cross-section, dimensions, material, mounting method, and contact surfaces—not just the equipment name.
- Use an existing part, drawing, or verified assembly measurement as the reference; treat illustrative dimensions as non-specifications.
- Ask the supplier to confirm the proposed profile and material against your application before approving production.
Who This Guide Is For
This guide is for drilling contractors, solids-control teams, maintenance departments, screen distributors, and procurement professionals sourcing replacement shaker components. It is especially useful when an original strip is worn, damaged, unavailable, or difficult to identify from a parts list. It can also help buyers prepare a more complete request for quotation (RFQ), reducing avoidable back-and-forth during part verification.
It is not a substitute for the equipment manufacturer’s parts documentation or a confirmed engineering drawing. If the strip is part of a safety-critical or load-bearing interface, follow the equipment supplier’s instructions and obtain technical approval before substitution. A supplier can assess the information you provide, but should not infer an exact fit from a product name alone.
What Is a King Cobra Shaker Rubber Strip?
Basic purpose and location
A shaker rubber strip is a shaped elastomer component used at a designated interface within a shale shaker or screen assembly. Depending on the design, it may provide a cushioning contact surface, help retain or locate a component, or reduce direct contact between parts. Its precise job depends on its position and profile, so buyers should identify the installed location before selecting a replacement.
“King Cobra” identifies the equipment or product family named in the purchasing request; it does not, by itself, establish the strip’s exact dimensions or construction. Confirm the model or assembly configuration from a nameplate, parts record, drawing, or the equipment supplier. If those details are unavailable, photographs of the installed location and the removed part can help a supplier begin a compatibility review.
Materials and Specification Details
Material options
Rubber compounds differ in properties such as hardness, resilience, and resistance to the fluids or environmental conditions they encounter. The appropriate compound depends on the application and the original design requirement; a visually similar material is not necessarily an equivalent replacement. If you know the original material specification, include it in your RFQ, and ask the supplier to identify any proposed alternative clearly.
Do not assume that a particular elastomer, hardness, or color is standard across every shaker configuration. Where the original specification is unknown, provide operating conditions and ask for a supplier recommendation subject to your technical approval. Material selection should be based on documented requirements rather than color or appearance alone.
What to specify in an RFQ
| Item to confirm | Information to provide | Why it matters |
|---|---|---|
| Equipment and position | Shaker model or family, assembly location, and part reference if available | Helps distinguish parts that may look alike but fit different locations |
| Profile and dimensions | Cross-section drawing or width, thickness, length, and shape details | Supports assessment of seating, contact, and installation fit |
| Material | Known compound or requested operating properties | Helps align the replacement with the service environment |
| Order requirements | Quantity, delivery destination, target date, and packaging needs | Allows the supplier to provide a relevant quotation and schedule |
How to Measure and Check Compatibility
Step 1: Identify the installed location
Record where the strip is installed and what it contacts. Take photographs of the overall assembly and close-ups of the strip in place, including any joints, bends, notches, grooves, or retaining features. If the part has been removed, photograph it beside a ruler and note whether it is distorted, compressed, torn, or stretched.
Step 2: Measure the original part
When possible, measure an undamaged section of the existing strip and compare it with a drawing or another verified part. Record the three primary dimensions—width, thickness, and overall length—in millimeters (mm), and note the cross-section shape separately. As a practical documentation method, take measurements at 3 points along the strip when its condition allows; variation may indicate wear, deformation, or a tapered design rather than a manufacturing specification.

A caliper readable to 0.1 mm can help document small profile dimensions, but the measurement tool does not determine the acceptable manufacturing tolerance. Record whether measurements came from a new part, a used part, or an equipment drawing. For a long or flexible strip, also note whether it was measured straight or while following a curve.
Step 3: Compare the complete interface
Check more than overall length. Compare the cross-section, edge shape, groove or lip details, installed orientation, and the surfaces that contact neighboring components. Confirm whether the strip is supplied as one continuous piece or as sections, and determine whether joints or end treatments are required by the assembly. If the original part is too damaged to measure reliably, request confirmation against a drawing, sample, or equipment documentation before ordering.
Step 4: Confirm the replacement before purchase
Send the supplier your measurements, photographs, model information, requested material, and quantity. Ask them to list the dimensions and material basis they intend to quote, and to flag any assumptions or unresolved compatibility questions. Review that information against your maintenance or engineering requirements before approving production or shipment.
Common Selection Mistakes
- Ordering by equipment name only: A family name may not identify the exact shaker configuration, assembly position, or strip profile.
- Measuring a worn section: Compression, abrasion, or stretching can make a used strip a poor dimensional reference.
- Checking length but not profile: A strip of the right length may still fail to seat correctly if its cross-section or retaining feature differs.
- Changing material without review: Similar appearance does not confirm equivalent performance in the operating environment.
- Leaving assumptions out of the RFQ: Missing model details, quantity, or destination can delay quotation and make offers difficult to compare.
Pricing, MOQ, and Lead Time
Pricing depends on factors such as the confirmed profile, material, order quantity, tooling or setup requirements, packaging, and shipping destination. Minimum order quantity (MOQ) and lead time are supplier- and specification-dependent, so they should be confirmed in the quotation rather than assumed from another order. If the part is needed for planned maintenance, share the required delivery date early and ask whether the supplier can meet it before issuing a purchase order.
For a custom or uncertain profile, ask whether drawing review or a sample is needed before production. Confirm who is responsible for approving the final dimensions and material, and request that the agreed specification be recorded on the quotation or order documentation. This makes supplier offers easier to compare and gives both parties a clearer reference if questions arise.
Supplier Evaluation Checklist
Choose a supplier that responds to the actual fitment questions, not just the product name. A useful supplier should be willing to review drawings, photographs, or samples; explain what information is missing; and state the specification behind the proposed replacement. Before purchasing, confirm the quoted quantity, dimensions, material description, packaging, delivery terms, and any inspection or documentation requirements your organization needs.
Yuanpeng supplies wire-mesh and related shaker components and can review buyer-provided drawings, samples, and application details for a rubber-strip inquiry. We recommend confirming the final specification and compatibility in writing before order release. Share the equipment information and target quantity with our team so we can assess what is needed to prepare a quotation.
Conclusion: Choose by Verified Fit, Not by Name Alone
The dependable way to replace a King Cobra shaker rubber strip is to verify its location, profile, dimensions, material, and mounting interface against the actual assembly or an approved reference. Measure and document the part in millimeters, distinguish worn-part readings from drawing dimensions, and disclose any uncertainty to the supplier. The equipment name is a useful starting point, but it is not sufficient proof of compatibility.
Your next step is to gather the model or parts reference, photographs, available measurements, material requirements, quantity, and delivery destination. Send these details to Yuanpeng for a compatibility review and quotation, then approve the replacement specification before purchasing. This process gives your maintenance and procurement teams a clearer basis for selecting a suitable replacement.
