1-1/4" NPT Triple Common Inlet/Outlet Sea Pump Adapter

• 316L Stainless Steel
• 1-1/4" NPT

At last modern technology has allowed us to again advance from a square block to an actual tuned water inlet manifold. These new cast and polished 316L Stainless Steel inlets feature staggered length and size high flow radiused inlet tubes that provide the ultimate in equal distribution provided by the massive 1-1/4"npt connection. Equal distribution to each chamber has long been a challenge that until now with modern precision flow technology and data acquisition monitoring was unavailable. Careful engineering was put into the design of both  the vacuum and pressure fed characteristics, The design and configuration of the inlet allows a easy access. The inlet is tucked in tight to allow for added clearance on many applications such as Catamaran style boats.these inlets are unmatched by anything available today in modern marine cooling system. These components are designed to assist in the plumbing of your engine when using the Hardin Marine Multi-Stage sea pumps. A wide range of configurations can be created by using different inlet and outlet adapters.
