THE SHORT ANSWER
Automotive weatherstrips seal door, trunk, hood and window openings against water, wind noise and dust. Most aftermarket buyers need one of three types: a pinch-weld seal (U-channel with a metal clip carrier and a sponge bulb), an EPDM door profile matched to the vehicle's section, or a self-adhesive windshield / roof strip. We supply universal profiles from 10 m and match vehicle-specific sections from a drawing or a sample.

Universal or OEM-shaped – which car weather stripping do I need?
Most aftermarket car weather stripping is universal: a straight extruded profile (pinch-weld seal, D-strip or windshield strip) sold by the metre and cut to length. It fits many vehicles as long as the flange thickness and the gap match. OEM-shaped seals are moulded for one model, with formed corners and clips, and are not sold as straight strips.
We supply universal profiles from 10 m and can extrude a vehicle-specific straight section from your sample or drawing; moulded corners for a particular model are quoted case by case. We do not use vehicle brand names or logos.

BUYER QUESTIONS
Automotive seals:
common questions.
Have a section in mind?
Dora can help with your enquiry.
01Do you make seals for a specific car model?
We match sections from a drawing, a clear cross-section photo or a physical sample of the old seal. We do not use vehicle brand names or logos on our products.
02What is a pinch-weld seal?
It is a U-shaped channel that grips the folded sheet-metal flange (pinch weld) around a door or trunk opening, usually with a metal clip carrier inside and a sponge bulb on top or at the side that the door closes against.
03Which grip range do I need?
Measure the total thickness of the flange, including any paint or trim. Edge trim is specified by grip range, for example 1–2 mm or 2–4 mm. See our edge trim grip range guide.
04What is the minimum order?
There is no minimum – standard profiles from 10 m. Indicative FOB prices start from US$0.10 per metre.
