The Expansion Joint People

RUBBER EXPANSION JOINTS. All designs availale: Hand-built wide arch, hand-built low profile super wide arch, low spring rate wide arch, PTFe lined molded arch, narrow and wide arch concentric and eccentric reducers and spherical types. Modifications to design inclued: Multiple arch and filled hand-built wide arch.  Standard elastomers include: Butyl, Neoprene, Nitrile, CSM (similar to Hypalon®), EPDM, natural and Viton®. Also available in PTFE and FEP. in-stock sizes range from 1” id to 72” id. manufacturing capability to 120” id. (Tooling is available to manufacture all non-stock sizes.)   Proco also supplies U-type expansion joints in rectangular, oval and round configurations with internal or external rubber flanges for Turbine/Condenser applications.  Request brochures: series 230, series 271, series 261R, series 231/BT, series 251/BT, series RC 231/221, series Re 231/221, series 240/242, series 403 and series 404.


PTFE EXPANSION JOINTS. Called Couplings, expansion Joints or bellows. Only PROCO offers in-stock sizes ranging from 1” to 12” in 2, 3 and 5 convolutions. PROCO offers sizes ranging from 1” id through 24” id in 2 and 3 convolutions and 1” id though 20” id in 5 convolutions. Designed primarily for chemical services, the inexpensive cost and short face-to-face lengths make these products universal in application. Request brochures: series 440.


RUBBER PIPE / VIBRATION DAMPENERS. For vibration/noise Reduction or lateral movements, PROCO rubber pipe is in-stock from 1” id to 24” id in lengths from 12” to 48”over-all length. standard stocked elastomers are Neoprene and Butyl, although other elastomers are available. Request brochure: series 300.


FLEXIBLE METAL HOSE CONNECTORS. Wire braid covered annular corrugated hose of stainless steel or bronze sweat end are in-stock in id sizes 1/2” to 14”. Available with flanged, grooved, threaded or sweat ends. special hose assemblies can be manufactured to customer specifications with: One braid or Two braids and a selection of end fittings. Request brochure: series 6201.

RUBBER CHECK VALVES. Rubber Check valves are cost effective way to control back pressure from effluent operations.  Offered as direct replacements for ineffective and maintenance-ridden flap type valves. sizes range in id from 1” to 84”.  Available in flanged or sleeve to fit on end of pipe. Also available as in-line rubber check valve. Request brochures: series 710/730, series 720/740, series 770/780.


PENETRATION SEALS. Where piping passes through a wall or floor, use an all rubber Pen-seal to statically seal annular space between wall/floor and pipe. Manufactured of EPDM, Nitrile and Silicone. bolting can be supplied with Zinc-plated Carbon  steel or 316 stainless steel. Request brochure: Pen-seal.




LOW TORQUE GASKETS. For Plastic, Fiberglass, glass or other piping which require minimum sealing forces. Manufactured in EPDM (with peroxide cure) and EPDM (with PTFE Film). in-stock sizes are available from 1/2” id to 12” id. Request brochure: series 9013.


NON-METALLIC DUCTING EXPANSION JOINTS / FAN CONNECTORS. PROCO manufacturers a complete line of ducting expansion joints available in round or rectangular sizes with flanged or flat belt profiles for fan inlet and discharge applications. elastomeric elements are offered for systems operating below 500°F and are manufactured of Viton®, Butyl, EPDM, Neoprene, Nitrile or Elastoplastic materials. Request brochure: series 500.

Proco Products, Inc. is a global leader in the design and supply of piping/ducting system expansion joints and rubber check valves.

Proco Products, Inc. also offers Proflex rubber check valves manufactured completely of rubber with top quality fungicide and barnable resistant rubber, and also provides valves which are manufactured from NSF/ANSI Standard 61 Certified materials.

CRP FluoroFlow PTFE Expansion Bellows

The bellows product range covers 19 sizes from DN25/1” to DN800/32”.  They are manufactured in two materials—virgin PTFE and static dissipating PTFE.  FluoroFlow Bellows in sizes DN25/1” to DN150/6” are available in extra heavy duty only.   

For larger diameters there is a choice of two wall thicknesses—a heavy duty (HD) and extra heavy duty (XHD).  The bellows can be manufactured with 2 to 10 convolutions.  However, this is just the standard product. The flexibility of the manufacturing method is such that many special configurations can be produced to meet specific customer requirements. ASME class 150, DIN PN 10 / 16 and other flanges types can be readily supplied.

For higher pressure rating products than PTFE alone can withstand we have our range of armoured bellows (FFAB) where the PTFE is surrounded by a high pressure retaining stainless steel shell.


We offer FluoroFlow bellows as an alternative to Fluroflex bellows.
