Weather-Resistant Compression Sealing

Rubber Door & Window Seals

EPDM and PVC rubber profiles in D, P, E, and T shapes for weather sealing of doors, windows, vehicle bodies, and industrial enclosures. Peel-and-stick or mechanical installation.

Product Overview

Compression Seals That Last Decades

Practak rubber seals are extruded from high-quality EPDM and PVC compounds and offered in a variety of profiles to match any gap geometry. EPDM grades provide superior resistance to UV radiation, ozone, and extreme temperatures from -40 °C to +120 °C, making them the ideal choice for exterior applications. Available with optional adhesive backing for fast peel-and-stick installation, or in plain profiles for mechanical clip or channel mounting.

Material: EPDM rubber / PVC rubber
Profiles: D-shape, P-shape, E-shape, T-shape, bulb seal
Temperature: -40 °C to +120 °C (EPDM)
Hardness: 55–70 Shore A
Features & Benefits
UV & Weather Resistance
EPDM rubber withstands prolonged exposure to sunlight, ozone, and rain without cracking, hardening, or losing elasticity.
Extreme Temperature Range
Rated from -40 °C to +120 °C, maintaining elastic sealing performance in cold-storage facilities, industrial ovens, and tropical outdoor conditions.
Compression Seal
Compression set below 25% ensures the seal fully rebounds after door/window closure, maintaining airtight and watertight performance for years.
Multiple Profile Shapes
D, P, E, T, and bulb profiles available to match any gap size and door/window geometry. Custom extrusion profiles on request.
Long Service Life
EPDM maintains elastic properties for 20+ years in exterior applications. Does not support microbial growth or rot.
Adhesive Backing Option
Self-adhesive versions with 3M-compatible acrylic PSA backing allow fast, tool-free installation on clean frame surfaces.
