White Polypropylene 20mm 90-Degree Barbed Elbow Skin Fitting for Marine Plumbing

This white polypropylene elbow fitting provides a threaded body with a 90-degree barbed hose connection for a hull or bulkhead installation. It is listed for hose with 20mm (3/4 inch) internal diameter. The elbow layout changes the hose direction close to the mounting surface, making it relevant where the hose needs to run alongside a panel rather than project straight away from it. The stated hose size should be compared with the inside measurement of the hose, while the mounting hole and body thread must be checked separately. Selecting an elbow involves both the connection size and the space available for the turn, the retaining arrangement and the hose fastening points.

Choosing and using this product

Check the hose specification against the 20mm (3/4 inch) connection before ordering. If selecting the dual-size version, confirm how the hose is to be seated on the stepped connection for the size you need. Measure the panel or hull thickness and obtain the fitting body and cut-out dimensions before making a new opening. Plan the final elbow direction so the hose can leave the fitting without a tight bend, twisting or pulling against the mounting surface. Allow room to reach the retaining hardware and to tighten and inspect the hose clamp. Choose bedding and assembly methods suitable for polypropylene and the material of the hull or bulkhead. Do not assume that a threaded plastic body has the same application limits as a metal skin fitting, and seek installation advice for any safety-critical or below-waterline location. Confirm any required pressure, temperature and fluid-compatibility limits with the supplier. Once installed, inspect the mounting joint and hose connection for leakage, support the hose along its route and retain access for maintenance.
