Copper Press fittings are NSF approved and certified to NSF/ANSI 61 and 372 with the certificate number C0297459-01. All fittings are manufactured from high quality copper and lead-free brass material. Sizes range from ½” to 4”. We offer more variety and versatile fittings to suit the needs of plumbers than any other brands in the market.
For water fittings, we use the EDPM O-ring (black) which is strong, flexible and resists decay. There is a broad range of seals providing good resistance suitable for different conditions such as aging, ozone, sunlight, weathering and hot water. It meets all the requirements of NSF/ANSI 61 and 372. All water fittings are suitable for drinking, heated and chilled water.
For gas fittings, we use the HNBR O-ring (yellow) which has attributes for physical strength and retention of properties particularly after long term exposure to heat, oil and chemicals. Fittings are suitable for natural gas, compressed air, fuel lines.
For high temperature application, such as those used in solar we use FKM ( Flurocarton) O-ring (red) for water temperatures ranging from 230 to 320 degrees Fahrenheit.
Copper Press fittings are suitable for the use with type K, L and M copper tubes provided it complies with copper tube conforming to ASTM-B-88.
