Parker Fittings and Port Adapters
Parker pipe fitting shaped products (elbows, tees and crosses) are hot forged and machined. Parker straight pipe fittings are manufactured from cold drawn barstock. Where applicable, the fittings are made in conformance with SAE J514, J530. All Parker steel pipe fittings are zinc plated with silver chromate (zinc chromium 6 free). Stainless steel pipe fittings are passivated.
