Hose bulkheads & Couplings

When connecting your heating unit with hoses and pipes for water flow, we have the products to help you do it neatly and effectively. We offer billet bulkhead fittings for both hose and AN connections. Our couplers allow you to change hose sizes between, for example, the circulation pump and the heater core.
In addition to these billet options, we also offer simpler plastic fittings including straight couplers, 90-degree bends, T-joints, Y-joints, and bulkhead pass-throughs.

The most common sizes in heating systems are 13mm, 16mm, 19mm, and 22mm.
