CPI Series Instrumentation Couplings offer exceptional sealing integrity and utilize positive valve stops to prevent flow checking and contain no solid lubricants which may contaminate samples. Available Valved or Unvalved, Keyed, and Color Coded.

The FS Series Instrumentation Dry-Disconnect is used extensively where spillage could cause undesirable conditions. Flush-face valving virtually eliminates fluid loss upon disconnection and air inclusion upon connection. Available Valved or Unvalved, Keyed, and Color Coded.

The "PF" Series Non-Spill Plastic Coupling is designed to meet the demand for closed system transfer and dispensing of chemicals with minimal environmental contamination.

The ST Series are non-valved couplings for applications where maximum flow is required. Their smooth, open bore offers the lowest pressure drop of any quick coupling design and is ideal for applications such as high pressure water and steam washers, carpet cleaners and mold coolant lines. They are often used in food processing, on fluid and dye transfer lines.

The 1141 Series high pressure coupling allows connection under pressure.

60 Series General Purpose Couplings are used across the spectrum of hydraulic applications. These Double Shut-Off couplings can be found anywhere that fluid  transfer lines need to be connected and disconnected for operation or maintenance of equipment, and a loss of fluid is undesirable. Primarily used with hydraulic fluid, general purpose Double Shut-Off couplings are also used with chemicals, water, steam, and some gases.

30 Series Couplers are designed for rigid mounting that allows a simple push-to- connect operation. Constructed of a solid brass body and a steel valve, 30 Series couplers are noted for their high flow capability, reliability and rugged design.

HF Series Pneumatic Quick Couplings offer an alternative to traditional industrial interchange couplers. The quality and durability you have come to expect from Parker 20 Series couplers, combined with a slim profile and push-to-connect design. The result is an easy to use general purpose pneumatic coupler suitable for use in a variety of applications.

HF NoMar™ Pneumatic Couplers offer all the features of our standard HF Series products, combined with a non-marking, oil resistant, polyurethane cover and port protector.  Features include: slim profile, push-to-connect operation, industrial interchange profile, and brass construction with corrosion resistant components.

E-z-mate Couplings combine push-to-connect, exhaust-style action with a self-locking valve sleeve to guard against accidental disconnection. Simply follow the direction of the On-Off arrow stamped on the yellow chromate valve sleeve. It’s that easy.

E-z-mate NoMar™ is an exhaust-style coupler designed to exhaust air pressure prior to disconnection. This allows for connection and disconnection at 0 psi, greatly reduces the force required to couple and uncouple, and minimizes the possibility of hazardous hose whip.
