Product Highlights

• Automatic air vent with shut-off check valve — PlumbEZ slimline brass self-bleeding float valve continuously releases trapped air from radiators, boilers & closed-loop central heating systems, reducing gurgling, cold spots and corrosion.
• Service without draining — Integrated shut-off/check valve lets installers remove or replace the vent without draining the circuit; ideal for boiler rooms, cylinders, manifolds, radiator risers & towel rails.
• Reliable float-operated mechanism — Opens when air accumulates and seals when water rises for low-maintenance, leak-resistant operation; fit upright/vertical at high points for best air elimination.
• Built for heating environments — Brass body suitable for typical domestic & light commercial hydronic systems; compatible with common corrosion inhibitors & glycol antifreeze blends.
• Compact, easy install — Slimline profile fits tight spaces and replaces traditional radiator bleed valves/boiler air vents; helps restore quiet circulation, balanced radiators and consistent heat output.
