Compression Couplings
An elegant solution for joining pipe and tubing for pneumatic conveying systems.
The compression tubing and pipe coupling is designed for permanent installation in the joining of either plain end, threaded, grooved, or a combination of any of these joints. The band-type construction holds the entire surface of the joint in uniform compression.
Couplings are made of heavy-gauge zinc-plated steel. Prices of aluminum or stainless steel couplings are quoted on request.
Gaskets furnished standard in black neoprene. FDA approved white neoprene and a variety of other materials at a slight extra charge, (please specify).
To Prevent Static Electricity Build-up in Bulk Material Conveying Systems, specify Morris Compression Couplings with grounding strips. Be sure to state if your requirements call for aluminum or stainless steel strips.
Stainless steel grounding strips are standard, aluminum grounding strips or couplings without grounding strips are available at the same price. To Eliminate Gasket Wear or contamination of material flowing through the system lines, specify Couplings with Stainless Steel GASKET PROTECTORS.
- Easy to install
- Pipe and tube sizes 1/2″ through 48″
- Standard construction material is heavy gauge zinc-plated steel
- Also available in stainless steel and aluminum
- Gasket materials: black and white neoprene, silicone and others
- Static conductive grounding strip is standard
To order: please specify the diameter for pipe or tube, number of bolts (or length), and gasket material (black or white food grade). Please let us know if you need a gasket protector as well.
