1/2" Press x Male Copper Union CP-12MU
- Press fittings are suitable for potable water, hydronic heating, chilled water, com- pressed air, non-medical gases, low pressure steam and vacuum
- Easy and rapid installation reduces valuable labor time.
- A permanent flame-free connection is made with no fire hazard.
- Press fittings are compatible with ASTM B88 (Types K, L, M) hard-drawn copper tube (1/2" to 4") and soft copper tube (1/2" to 1-1/4”) . (When soft tube is used, rounding and sizing of the tube ends must be performed where needed.)
- Certified by leading international approval authorities.
- Maximum working pressure 250 PSI
- Maximum working temperature 32ºF-200ºF
- Sourced in full compliance with relevant standards, only the highest quality raw materials are used in manufacturing.
- Un-pressed fittings are easily identified with Leak Before Press technology built into the sealing elements.
- System is compatible with most common press tools and jaws in use.
- 50-year product warranty.
- Threaded tees are arc-welded for a stronger and more consistent connection.
- All press tees are manufactured in one-piece and are tested individually before packaging.
