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.
PT Coupling does not recommend cam and groove fittings for compressed gas service, including air and steam.
