THE SHORT ANSWER
Custom rubber parts are extrusions or moulded parts made to your own section rather than picked from a catalogue: sponge or solid EPDM profiles, high-temperature silicone seals, co-extruded hard + soft profiles, sponge cords, cut gaskets and moulded rings. To quote we need a drawing or clear cross-section photo with key dimensions, the application, the material or performance requirement and an estimated quantity. For most custom profiles tooling and samples are free – you only pay the courier; sampling takes 7–10 days.

BUYER QUESTIONS
Custom parts seals:
common questions.
Have a section in mind?
Dora can help with your enquiry.
01What do you need for a quotation?
A drawing or clear cross-section photo with key dimensions, the application, material or performance requirement (temperature, outdoor use, food contact, hardness), estimated quantity and packing needs.
02Is there a tooling fee?
For most custom profiles made from your drawing or dimensions, tooling and samples are free – you only pay the courier. Very complex parts may carry a sample fee on the first order, refunded on your repeat order.
03How long do samples take?
Sampling takes 7–10 days; mass production takes about 20 days per 40GP container.
04Can you match a sample I already have?
Yes. Post the sample or send clear photos of the cut end next to a ruler; we measure it and propose a profile.
