The latest news from Harltex

Harltex reflects on the Defence Procurement Conference and the growing role of UK SMEs in supporting defence supply chains through specialist sealing, extrusion and moulding expertise.

In precision rubber extrusion, maintaining tight rubber extrusion tolerances depends heavily on material selection. Rubber extrusion tolerances refer to the allowable dimensional variation in an extruded rubber profile during manufacture.

Selecting the correct elastomer is often a balance between temperature resistance, chemical compatibility and cost. It is rarely about choosing the “best” material overall, but rather selecting the right compound for the operating environment.

2025 marked a year of steady progress for Harltex. Alongside celebrating the milestone of 40 years as a specialist UK manufacturer of rubber extrusions and profiles. While the anniversary provided an opportunity to reflect on decades of manufacturing expertise, the focus remained firmly on key principles.

The reliable Elastomer for Oil, Fuel & Industrial Applications. EN682 Gas NBR, also known as Buna-N, is a synthetic rubber made from acrylonitrile and butadiene. Its oil resistance, durability, and cost-effectiveness make EN682 Gas NBR one of the most widely used elastomers across industries.

At Harltex, we’ve combined decades of expertise in engineered rubber with the latest material science. VIT700 is not just another FKM—it’s a carefully developed compound that provides a balance of strength, resilience, and resistance across multiple environments.

This year marks a major milestone for Harltex Ltd — 40 years of precision-engineered rubber mouldings, extrusions, and bonded products, evolving with the industry, and pushing the boundaries of what’s possible.
