Product Overview

A rectangular rubber plug with holes combines an outer fitting profile with several internal passages. The rectangle locates the component in the assembly, while the holes need to align with the items or openings they serve. Their positions should therefore be defined from the same reference features as the external profile.

Compression molding can develop a neoprene or other selected rubber configuration around those requirements. Consider the material between neighboring holes as well as the overall dimensions, and check whether seating the outer body changes the passage shape.

Trial the plug in its intended orientation before routing the mating components through it. Avoid using a reversed rectangular outline simply because it can be pressed into the opening; the hole positions may no longer match the design. After assembly, inspect for a pinched passage or a retained edge that has lifted. Keep the routed items independently supported where required so their combined weight or movement does not distort the molded plug within its seat.

Material options: Neoprene compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. Compression molding can develop a neoprene or other selected rubber configuration around those requirements.
Custom geometry: Consider the material between neighboring holes as well as the overall dimensions, and check whether seating the outer body changes the passage shape.
Fit evaluation: Keep the routed items independently supported where required so their combined weight or movement does not distort the molded plug within its seat.
Color & OEM: Custom colors; OEM identification positioned outside closure contact surfaces.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
