Product Overview

An aluminum window rubber gasket follows a sealing interface within the window frame assembly. The aluminum profile, corner arrangement and mating component determine the shape required. A gasket that fits along a straight section still needs to remain properly seated where the frame changes direction or meets another part.

Select the rubber compound for the exposure at that position, including outdoor conditions and the cleaning products used on the frame. Develop the profile around the actual channel or contact face, and check the available movement when the window closes or is assembled.

Fit the gasket without stretching a length to reach the next corner. Keep the frame's designed drainage and operating features clear, and inspect the contact path after surrounding trim is installed. For replacement, compare the intended profile with the channel rather than relying only on an aged piece removed from it. If a corner repeatedly pulls away, examine the joint geometry and installation length before using additional material to cover the gap.

Material options: Rubber. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. Develop the profile around the actual channel or contact face, and check the available movement when the window closes or is assembled.
Custom dimensions: The aluminum profile, corner arrangement and mating component determine the shape required.
Fit & assembly: A gasket that fits along a straight section still needs to remain properly seated where the frame changes direction or meets another part.
Use & inspection: For replacement, compare the intended profile with the channel rather than relying only on an aged piece removed from it.

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.
