Parker’s CPI™ compressor couplings with a single sealing ring provide a leak-free connection for process, power, and instrumentation applications. These pipe couplings feature a single sealing ring for easy assembly and excellent performance in vibrating applications. The “spring-loaded” effect of the single sealing ring creates constant tension between the coupling and its nut.

The CPI™ pipe coupling is made of 316 stainless steel with a traceable heat code. Other corrosion-resistant alloys include 6Mo and Alloy C-276 (also known as Hastelloy C®). Straight couplings are machined from cold-drawn bar stock, and formed units are machined from fine-grained billets.

The fittings are available in British pipe sizes (outer diameter 1/16 inch to 2 inches) and metric pipe sizes (outer diameter 2 to 25 mm). These adjustable pipe fittings are manufactured to the industry’s highest quality standards.
