Coliter ® Air Vent Plug 2511004.0110, PN16, 100°C, Lead-Free Brass, for Manifold Systems
2511004.0110 Air Vent Plug – Compact End Cap with Integrated Automatic Air Vent for Hydronic Manifolds
The Coliter® 2511004.0110 Air Vent Plug is a specialized end-piece component designed for underfloor heating and hydronic manifold systems. It combines a sealed end cap with an integrated automatic air vent to continuously release trapped air from the highest point of the circuit—preventing airlocks, noise, and reduced heating efficiency. Constructed from high-quality lead-free brass, it ensures corrosion resistance and long-term reliability. Rated for a maximum working pressure of PN16 (1.6 MPa) and temperatures up to 100°C, it is available in standard sizes DN25 (G1") and DN32 (G1¼"). The plug threads directly into the end port of Coliter® or compatible manifolds, providing a clean, maintenance-free solution for system deaeration without the need for additional fittings or manual bleeding.

Introduction to End Piece
Coliter®’s end piece assemblies are essential safety components for underfloor heating and hydronic manifold systems, integrating an automatic air vent, drain valve, and end tee into a single compact unit. The assembly automatically releases trapped air at the highest point of the circuit while enabling quick drainage for maintenance, pressure testing, or winterization. Available in DN25 (G1") and DN32 (G1¼") sizes with lead-free brass construction, it ensures reliable operation up to PN16 (1.6 MPa) and 100°C. Compatible with standard manifold headers—delivering system stability, easy servicing, and long-term protection against airlocks and sediment buildup.
