End Plug 3/4"
These plastic adapters cap off a 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 R5and Leybold SogeVac SV pumps). Do not use these fittings on dual stage vacuum roughing lines or high vacuum applications.
