Air Unions
Parveen's Air-Unions are designed for 150 PSI maximum line pressure.
Features:
- Air inflates tube to seal around pipe.
- Fast and easy makeup without close alignment
- Allows Pipe expansion or misalignment (12'-15') without breaking the seal.
- No wrenches, bolts & nuts required.
- Available in 4", 6", 8", 10", 12", 13" & 16" sizes.
- Line Pressure = 150 PSI(max)
Tube Pressure = Line Pressure + 50 PSI
= 150 + 50 = 200 PSI(max)
Parveen exclusively manufactures Hammer Unions in India.
