PlumbEZ 15mm Compression Automatic Air Vent

PlumbEZ 15mm Compression Automatic Air Vent

The PlumbEZ Slimline Automatic Air Vent (15 mm Compression) is a compact, float-operated self-bleeding valve that continuously removes unwanted air from radiators, boilers and closed-loop central heating systems. Entrained air is a common cause of noisy pipework, radiator cold spots, corrosion, pump cavitation and sluggish circulation. By automatically venting air as it accumulates, this automatic air eliminator helps your system run quieter, improves heat transfer and reduces the need for routine manual radiator bleeding.

Key Features

• Automatic air vent for radiators & boilers — PlumbEZ slimline brass self-bleeding float valve continuously releases trapped air in closed-loop central heating systems, reducing gurgling, cold spots and corrosion.
• 15mm compression connection — Quick, secure fit to standard 15 mm copper or barrier pipework; ideal for boiler flow/return headers, radiator risers, airing cupboards, towel rails and distribution manifolds.
• Reliable float-operated mechanism — Opens when air accumulates and seals when water rises for low-maintenance, leak-resistant operation; install upright/vertical at high points for best air elimination.
• Durable brass construction — Built for domestic and light commercial hydronic environments; compatible with common corrosion inhibitors and glycol antifreeze blends used in sealed systems.
• Compact, easy install — Slimline profile fits tight spaces and replaces manual radiator bleed valves/older boiler air vents to restore quiet circulation, balanced radiators and consistent heat output.
