Made with lightweight nylon sleeves, these gear couplings require less energy to move than other high-torque flexible couplings. They compensate for parallel, angular, and axial misalignment.

Install and remove these shaft couplings without disconnecting the shafts, motors, and other attached components—they’re made in two pieces so you don’t need to slide them onto shaft ends. They’re also useful when you have limited access to the ends of the shafts.

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.
