Overview
PT 05A couplings are quick-connect/disconnect cam & groove fittings engineered by PT Coupling, a U.S.-based manufacturer with over 70 years of industry experience. PT Coupling manufactures and distributes American made quick connect/disconnect couplings and replacement parts for the Petroleum, Industrial, Chemical and Food Grade markets. The 05A is part of PT’s standard flexible coupling line for applications requiring secure, tool-free connection and disconnection of hoses, adapters, and fluid transfer systems.
Key Features
- Quick-connect/disconnect operation via cam and groove mechanism—no tools required
- Camming action allows pipe and hose connections to be made without the need of hand tools or difficult threaded connections
- Two-part assembly: male adapter (plug) and female coupler (socket) that lock together under pressure
- Standard Buna N gaskets for reliable sealing
- Manufactured in the USA with quality control and pressure testing
Technical Specifications
Standard gaskets are Buna N any variation must be specified. Verify exact sizing, material composition, and pressure rating with PT Coupling or your system integrator, as the 05A designation may refer to a proprietary size or variation not listed in standard public catalogs.

Compatibility & Replacements
Compatible With
- Male (adapter/plug) and female (coupler/socket) that work together — PT 05A couplers pair with compatible male adapters of the same size designation
- Standard hose barbs, threaded NPT ends, and flange-mount configurations (verify specific variant)
- Water, hydraulic oil, coolants, gasoline, and petroleum products
- Industrial hose assemblies and fluid transfer systems meeting MIL-C-27487 or A-A-59326 standards
Replaces / Drop-In Replacement For
The PT 05A is interchangeable with cam & groove couplings of equivalent size and specification that conform to MIL-C-27487 or A-A-59326 standards. Pro Flow Camlock fittings are fully interchangeable with PT couplings, Dixon camlock fittings, OPW camlock fittings and Banjo camlock fittings. However, verify model compatibility with your distributor or system integrator before ordering.
Works With
- Standard industrial hose assemblies (1/2″ to 6″ nominal sizes, depending on variant)
- MIL-C-27487 / A-A-59326 certified equipment and systems
- PT Coupling adapters, caps, plugs, and replacement gasket kits
- Male adapter plugs with matching groove profile
