Medical Grade PTFE Components and Custom Polymer Solutions for the Pharmaceutical Sector

Beldam Crossley:

Specialists in Chemically Inert, Sterile, and Food-Safe Sealing and Polymer Components

At Beldam Crossley, we manufacture precision-engineered PTFE and polymer components for the medical device and pharmaceutical manufacturing industries. Our solutions range from bespoke seals for OEM medical equipment to chemically resistant gaskets and diaphragms for pharmaceutical processing systems.

Backed by over 100 years of engineering expertise, we support both standard and custom component requirements—manufactured in the UK to the highest global standards.

PTFE Components for Medical and Pharmaceutical Applications

Our PTFE and Crossflon® components are trusted for use in sterile, hygienic, and chemically aggressive environments. Designed to handle demanding conditions, they are:

Chemically inert – Non-reactive with pharmaceuticals, solvents, acids, or cleaning agents.
Food and medical grade – Safe for direct contact with medicines, fluids, and active pharmaceutical ingredients (APIs).
Temperature resistant – Operational from -240°C to +200°C.
Low-friction and self-lubricating – Ideal for hygienic seals and dry-running mechanical applications.

All materials are compliant with applicable food, pharmaceutical, and environmental standards (ISO 9001, ISO 14001, AS9100).

Custom Polymer Components for OEM Medical Equipment

Beldam Crossley works closely with medical OEMs to provide:

PTFE diaphragms for dosing systems, fluid handling, and pressure control
Rotary shaft seals and O-rings that minimise friction and contamination risk
Crossflon® dry-running bearings for ventilators, lab equipment, and surgical devices

Our in-house design support enables collaborative development and rapid prototyping for new technologies and product improvements.

Sealing Solutions for Pharmaceutical Manufacturing

We also serve pharmaceutical processing and packaging environments with long-lasting, contamination-free components, including:

Envelope gaskets – PTFE-clad seals that handle aggressive cleaning agents and irregular flange surfaces
Chevron sets and valve seats – Pressure-responsive seals for process control valves and pump systems
PTFE bellows – Flexible joints that absorb vibration and thermal expansion in sterile production lines

These components are critical for maintaining containment, preventing contamination, and ensuring GMP compliance in pharmaceutical plants.
