1-1/2" Air Vent | WTR704800001

Key Features

• The model AV-150 uses a semi-hard, precision ground, inert solid plastic float ball
• The float seats against a precision "O-ring" providing a tight seal at very low pressures where other vents often leak
• They have excellent seating characteristics and operate trouble-free at pressures up to 150 psi on the 1-1/2 in. and 2 in. units and 100 psi on the 3 in. and 4 in. units
• The aerodynamic "air flow" design of a high strength alloy aluminum body and full baffle assures maximum vent capacity without premature closing, material selection prevents "sticking" in the closed position
• Units are furnished with standard female pipe threads which should be protected with "Never-Seize" or equivalent when installed
