Female Adapter 1/2”
These plastic adapters are designed to make connections between NPT and rubber hose. (CAUTION -The hose must be made of a stretchy type of material, that is, the hose barb on these connectors is a little oversized to fit snuggly inside the hose. These hose barbs will not fit in Clear Steel Spring Reinforced PVC Hose). These plastic adapters work well as cost-effective exhaust line fittings and intake fittings on Rough Vacuum Applications (use as intake fittings on single stage pumps only, e.g., Busch R5 and Leybold SogeVac SV pumps).
