Metal Bellows

Metal Bellows provide stable, long-lasting solutions to many problems involving harmonics, vibration, high-temperature expansion, and/or cryogenic applications. Our unique forming and finishing methods permit fast completion of bellows in a broad variety of sizes, materials, movements, and spring rates.

An important aspect in our ability to provide complete solutions to our customers' applications is our ability to manufacture a broad array of fittings, refractories, and accessories for all applications. Dual bellows, special flanges, liners, insulation jackets, and covers pose no problems. Likewise, we can equip your bellows with wire braid, purge fittings, anchors, limit-rods, and root-rings just to name a few.

Whether you need a specific custom fitting solution, or as part of an overall system, GFab is ready to help you specify and manufacture the right parts for you.
