Plumbing Fittings

In a heating system the boiler and the pump are the visible heroes; the fittings are what quietly keep it alive. The air vent that expels air, the separator that traps sludge, the safety valve that limits pressure and the filling valve that keeps the system at the right pressure — each is small but critical in preventing failure. This category holds the Caleffi hydronic fittings family.
