KAN-therm plumbing tee with automatic air vent and drain valve G1 R5541

The KAN-therm plumbing tee with automatic air vent and drain valve G1 R5541 is a compact fitting engineered to remove trapped air and allow controlled draining in heating and plumbing systems. Designed for G1 threaded connections, this tee integrates an automatic air vent to expel accumulated air pockets and a manual drain valve to isolate and empty selected sections. It is intended for use in pipe runs, manifolds and radiator branches where reliable air elimination and safe draining support system efficiency and maintenance access.

Advantages

The integrated automatic air vent continuously releases entrapped air without manual intervention, reducing noise and improving circulation. The built-in drain valve enables a safe and fast way to empty a section for maintenance or repair. The combined function in a single compact tee minimizes the number of fittings required and simplifies installation in tight spaces. The product is compatible with standard G1 threaded connections, making it suitable for many common plumbing and heating layouts.

Suitable for

• Residential and commercial heating systems where air removal is required
• Manifolds and distribution headers to vent and drain individual circuits
• Radiator branches or return lines to purge air and perform sectional draining
• Pipe runs that require local draining during maintenance or system commissioning

Key specifications

• Connection type: G1 threaded
• Integrated components: automatic air vent and manual drain valve
• Application: plumbing and heating system air removal and section draining
• Installation orientation: inline tee for pipe runs, manifolds or branch lines
• Construction: compact combined fitting to reduce installation footprint

How to use

Install the tee into the piping system using the G1 threaded connections, ensuring proper sealing and alignment with the pipeline or manifold. The automatic air vent operates continuously once the system is pressurized, allowing air to escape while the system is running. Use the drain valve to isolate and drain the selected section by opening it to release water; close the valve after draining and retighten any seals as required. Follow system-specific procedures for depressurizing and refilling to avoid introducing new air pockets.

Usage recommendations

Position the tee at high points or at the end of branches where air tends to collect, and ensure the drain valve is accessible for maintenance. During commissioning and after servicing, bleed the system gradually and check the air vent function. Use compatible sealing materials on the G1 threads and inspect connections periodically for leaks or signs of wear.
