SD-55/4-O DGP Self-Adhesive EPDM Gasket D-Profile 14x12mm Black 40m Roll

Product Overview

The Uszczelka samoprzylepna DGP 14x12 czarna SD-55/4-O DGP 40m is a self-adhesive sealing gasket designed for acoustic and thermal insulation applications. Typically used by building contractors, window manufacturers, and HVAC installers, this product features a D-profile shape with dimensions of 14x12 mm and comes in 40-meter rolls. It is made from EPDM rubber, known for its high elasticity and performance across a broad temperature range, maintaining effectiveness from -40°C up to +65°C.

A key differentiator for this model is its EPDM rubber base, which ensures long-term elasticity and reversible deformation even under repeated cycles of compression and temperature variation. This eliminates the risk of seal hardening or cracking in demanding environments, reducing long-term maintenance costs. The product is well-suited for bulk procurement by facilities managers and manufacturers who require reliable, long-lasting sealing for doors, windows, or technical enclosures in harsh or fluctuating climates.
