Product Overview

A rubber sink plug can be customized as a solid block stopper for a selected sink opening. The working profile needs to suit the opening at its contact depth, while the exposed portion should remain easy to remove. Matching only the visible rim can leave the stopper seated too high or pushed farther in than intended.

Check the sink fitting for a taper, step or internal feature that limits insertion. Position the plug so it engages the intended surface without forcing it against the structure below. Material, dimensions and color can be selected around the fitting and the water and cleaning conditions involved. Keep the rim clear of residue before fitting the stopper. After use, remove it by the intended gripping area and clean the contact band rather than scraping it against the drain edge. If the plug develops a cut or becomes difficult to seat consistently, replace it with the correct profile. A tighter push should not be used to hide a damaged or mismatched sealing surface.

Material options: Rubber compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. The working profile needs to suit the opening at its contact depth, while the exposed portion should remain easy to remove.
Custom geometry: Matching only the visible rim can leave the stopper seated too high or pushed farther in than intended.
Fit evaluation: Check the sink fitting for a taper, step or internal feature that limits insertion.
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.
