Description Raychem Metal Coupling Pieces, c. 1957-1999. Two metal alloy couplings cut in half. (A) is a thicker alloy metal tube with one side cut clean and on the other side ragged. (B) is a thinner metal. The outside is smooth, and it has a "4" scratched by hand into the center. An inch long oblong hole is cut on each side. Inside, the metal is ribbed, but smooth in the center.

Raychemer Leon Hansen notes that Cryofit couplings were used on hydraulic lines in aircraft, particularly the Grumman F-14 Tomcat fighter aircraft.

Notes "Raychem was founded on January 1, 1957. It grew rapidly by creating proprietary new products based on Radiation processing of polymers to meet critical and difficult industry needs for electrical circuit integrity in harsh environments. Included in these initial products were irradiated wire insulation and heat shrinkable tubing. Markets included Aerospace, Military, Automotive, Telecommunications and Electrical Power Generation markets.
"In 1968, Raychem acquired Chemelex leading Raychem to extend its radiation polymer processing technology to polymers filled with conductive carbon creating a family of "Self Limiting Heaters". This technology was further extended to produce resettable switches forming the enabling technology for the "Polyswitch" Division.
"As Raychem grew into a world class Material Science Company, additional technologies explored, developed and taken to market were Heat Recoverable Metals, Piezoelectric Materials (Elographics), Silicone Gels (Geltek) and Liquid Crystals (Taliq).
"Each year, Raychem devoted between 8 and 10 percent of sales into Research and Development resulting in thousands of new products based on the technologies listed above. Research and Product Development labaratories, in addition to Menlo Park and Redwood City were established in Swindon, UK, Kessel-Lo, Belgium, Ottobrunn, Germany, Pontois, France and Japan.
"Manning these laboratories were an extremely creative and talented group of scientists and engineers who found innovative ways to use technologies to create new products."
