Air Vent / Automatic Air Release Valve ENIX model S-061-005 G1/8 with O-ring

ENIX S-061-005 is an automatic air release valve with a G1/8 threaded connection and integrated O-ring seal. It is designed to remove trapped air from closed fluid systems and to maintain continuous, leak-free operation in heating, cooling and plumbing installations. The compact G1/8 size and sealed design make the valve suitable for confined spaces and for systems that require reliable automatic purging of microbubbles and accumulated air.

Advantages

The automatic mechanism vents air continuously without manual intervention, reducing the risk of air locks and improving system efficiency. The integrated O-ring provides a secure seal at the threaded connection, helping to prevent leaks even under variable pressure and temperature conditions. The compact design and standard G1/8 thread ensure straightforward installation into existing manifolds, radiators, pumps or pipe runs with compatible ports.

Suitable for

• Domestic and commercial heating systems (radiators, underfloor heating manifolds)
• Chilled water and HVAC circuits
• Plumbing loops and closed-loop fluid systems
• Pump stations and circulation circuits where automatic air purging is required

Key specifications

• Thread connection: G1/8 (standard BSPP thread form)
• Sealing: integrated O-ring for leak prevention
• Function: automatic air release / venting of trapped air
• Application environment: compatible with heating, cooling and plumbing fluids
• Size and form factor: compact inline vent suitable for confined installation spaces

How to use

Install the valve into a compatible G1/8 threaded port on the system component, ensuring the O-ring is correctly positioned to create a watertight seal. Tighten to the recommended torque for the mating material to avoid damaging the thread or O-ring. The valve operates automatically: as air accumulates at the high point or vent location, it is released through the valve outlet. Periodically inspect the valve and surrounding connections for signs of leakage or wear and replace the O-ring if the seal degrades.

Usage recommendations

Fit the valve at system high points or on manifolds where air naturally collects. Use compatible thread sealants or installation practices appropriate for G1/8 connections only if they do not interfere with the O-ring sealing surface. Perform routine checks after initial installation and during scheduled maintenance to confirm free venting and intact sealing.
