Description
The PT Coupling A-Adapter is the standard Type A cam and groove fitting: a grooved male adapter on one end and a female NPT thread on the other. It mates with any Type B, C or D coupler of the same size. Use it for quick, tool-free connections on hose, pipe, tanks and pumps.
Key Features
- Made in the U.S.A. by PT Coupling
- Connects and disconnects without tools: insert the adapter into the coupler and close both cam arms to seal against the gasket
- Built to interchange with A-A-59326 cam and groove fittings in 3/4″ through 4″ and 6″; 1/2″, 5″ and 8″-12″ may not interchange across brands
- Stainless steel fittings are 316 stainless steel

Choosing a Material
- Aluminum: lightweight and economical with good abrasion resistance; for water, hydraulic oil, coolants, gasoline and petroleum products.
- Brass: good corrosion resistance at a lower cost than stainless and forms tight seals; ideal for water, and also used with hydraulic oil, coolants, gasoline and petroleum products.
- 316 Stainless Steel: excellent corrosion resistance and strength at high temperatures, and helps prevent product contamination; for salt water, waste water and many chemicals.
- Ductile Iron: excellent abrasion and wear resistance with good strength and toughness; for sand, grout, cement and other abrasives.
- Polypropylene: glass-fiber reinforced (black) with good abrasion, corrosion and chemical resistance; for water and coolants.
- Food Grade Polypropylene: white polypropylene for water and food-grade applications.
- Nylon: glass-fiber reinforced (green) with good abrasion, corrosion and chemical resistance; for water, coolants, gasoline and varnish.
- Hastelloy C®, Monel® and Carpenter 20®: for highly corrosive media such as hydrochloric and sulfuric acid.
