Details

SQDC couplings provide a fast and reliable way to connect multiple pneumatic lines where high temperature and vibration are present, such as flight test and harsh industrial environments. Bodies are machined from 316 stainless steel and accept either stainless-tube compression fittings or bulged tubulations for flexible tubing. Two primary seal families are offered to match temperature needs. Anti-vibration locking keeps the connection secure under mechanical stress. The range includes mating blanks, pipe-work guides, and mounting options to simplify panel integration and service.
