The LEGACY MANUFACTURING RP900500S is a reusable air hose end fitting with a swivel design, built for field assembly and hose repair. Featuring a 1/2 inch barb connection and a 3/8 inch male NPT (MNPT) thread, this fitting allows technicians and tradespeople to assemble a custom-length hose or restore a damaged hose end without special crimping tools. The swivel configuration reduces kinking and torque stress at the connection point during use. At 0.236 pounds, it is a compact, lightweight component suited for daily jobsite use across HVAC, plumbing, and general mechanical trades.
This fitting is designed for use with Flexzilla Pro air hose assemblies and is well-suited for repair or custom-length hose builds on residential and commercial jobsites. The reusable design makes it practical in service van environments where a quick hose repair is preferable to carrying a full replacement hose. Trade professionals working with compressed air systems will find this fitting compatible with standard 3/8 inch NPT air tool and compressor outlet connections.
Designed for use with Flexzilla Pro air hose. Refer to Legacy Manufacturing documentation to confirm hose inner diameter compatibility before installation.
Installation is performed by HVAC technicians, plumbers, or general mechanical tradespeople working with compressed air systems. Depressurize and disconnect the hose from the air source before disassembling or installing any fitting. Follow the three-step assembly process outlined in the product instructions to ensure a proper seal. Inspect the barb connection for full seating before returning the hose to service.
