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.
