Rubber Diaphragms

We design and mold custom rubber diaphragms for the toughest pressure, temperature and cycle-life demands. When a diaphragm has to survive millions of cycles without failing, engineers bring us the problem others can’t solve.

Every part made to your spec · Made in USA

Overview

Engineered for millions of cycles

ARC manufactures custom rubber diaphragms in five core configurations — reinforced, pump & valve, rolling, PTFE-coated and metal-bonded — each engineered for the pressure, media and cycle life of its application. We reinforce with Nylon, Dacron, Nomex, Kevlar or cotton fabric, bond to stainless steel, brass and other alloys, and add PTFE facings for chemical and abrasion resistance. Built for extreme pressures and temperatures and long operating life, our diaphragms serve high-frequency pneumatic and hydraulic systems where reliability is non-negotiable — every part custom-to-spec, Made in USA, under ISO 9001:2015 and IATF 16949:2016.

What we make

Diaphragm configurations we build

Reinforced Diaphragms

Fabric-reinforced (Nylon, Dacron, Nomex, Kevlar, cotton) for high-pressure strength and stability.

Pump & Valve Diaphragms

Custom diaphragms for pumps, valves and flow-control devices with long cycle life.

Rolling Diaphragms

Convoluted rolling designs for long-stroke, low-friction, high-cycle actuation.

PTFE-Coated Diaphragms

PTFE-faced diaphragms for chemical, abrasion and media resistance.

Metal-Bonded Diaphragms

Bonded to metal inserts — studs, washers, threaded nuts — for direct assembly mounting.
