(a division of Rex International USA, Ashtabula, OH), designed for pressure testing water lines, plumbing systems, heating systems, and other piping assemblies. The pump features a die-cast aluminum pump body, an integrated pressure gauge, a pressure relief\/bypass valve, and standard garden hose (GHT) inlet connection visible in the product photo, with a 3-prong 120V AC power cord for standard outlet operation. It is purpose-built for contractors and plumbers who need to hydrostatically test pipe systems to verify integrity — the motor drives a positive-displacement plunger pump that builds and holds test pressure while the bypass valve protects against over-pressurization. Grainger cross-references this unit under item number 6GDV5, confirming OEM identity. The unit ships new in original Wheeler-Rex factory carton.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
