Oase 42750 Bulk Head Fitting

The Oase 42750 is a bulk head fitting designed for 3/4 inch hose connections in plumbing and pond systems. It suits installers and maintenance teams who need a reliable through-wall or through-liner penetration for water circulation.

Cable Fitting Gasket and Stepped Hose Fittings

The bundle includes a cable fitting, gasket and stepped hose fittings that adapt the connection to the hose without extra parts. These components create a watertight seal and simplify the transition between the bulk head and the 3/4 inch hose.

Straightforward Installation With Seal Attention

Installation involves mounting the fitting through the wall or liner and tightening the supplied gasket to prevent leaks. The most common issue is an uneven seating surface that compromises the seal, so the mounting face must be clean and flat before final tightening.

Questions about this item

Does the 42750 bulkhead fitting require periodic gasket replacement to maintain a watertight seal?

The supplied gasket creates the initial seal; inspect it during routine pond maintenance and replace it if it shows cracking or compression set.

What is the first limitation encountered when the 3/4 inch hose fitting runs continuously under pump pressure?

The stepped hose barb and gasket joint determine the maximum sustainable pressure before leakage occurs.

How much heat does the 42750 fitting add to the water when the pump operates all day?

The fitting itself adds negligible heat; water temperature rise comes from the pump motor, not the bulkhead.
