WHEELER-REX

About WHEELER-REX

Wheeler-Rex is a manufacturer of pipe tools, pipeline equipment, and hydrostatic test pumps, with a product history that spans more than a century in the pipe trades. The company's catalog covers manual and powered pipe cutters, reamers, bevellers, pipe wrenches, vises, stands, and a range of specialty tools for maintenance and fabrication. Alongside these tools, Wheeler-Rex produces hydrostatic test pumps used to pressure-test piping systems, valves, and pressure vessels, and it supplies the repair parts and consumables that keep those pumps in service. 3G Electric stocks more than 160 Wheeler-Rex SKUs, including cutters, reamers, and repair parts, and supports buyers who need to match a specific tool or kit to an existing pump model or pipe size.

The hydrostatic test pump line is organized around model numbers such as 35100, 46501, 46800, 47105, 466000, and 373080, with repair kits identified by manufacturer part numbers including 34052, 34053, 36345, 36347, 36361, 36390, 36395, and 39350. These kits contain components such as Desmopan piston diaphragms, O-rings, O-ring adapters, piston cap screws, and accumulator diaphragms. Maximum discharge pressure ratings across the kits we list range from 300 psi to 3,000 psi, so the correct kit depends on the pump model and the pressure class of the test being performed. Desmopan is a thermoplastic polyurethane elastomer used for diaphragms where flex life and resistance to oils and fuels matter; it is a material selection detail that buyers should note when ordering replacement parts.

For pipe work, Wheeler-Rex tools are built around the mechanics of cutting and preparing pipe in the field and in the shop. Cutters are sized to specific pipe diameters and wall thicknesses, reamers deburr the inside of pipe after cutting, and bevellers prepare weld edges. The tools are mechanical in operation, which means the specification that matters most is the pipe size range and the material being cut. Buyers should confirm the tool's rated capacity against the actual pipe outside diameter and wall thickness before ordering, because a cutter rated for a nominal pipe size may not cover the same size in a heavier wall schedule.

3G Electric supplies the Wheeler-Rex line as part of its industrial equipment catalog, which also includes industrial burners, pumps, gas controls, and related components. For Wheeler-Rex, the practical support is in part identification: matching a repair kit to a pump model, confirming the included components and pressure rating, and cross-referencing manufacturer part numbers. The repair kits we list are model-specific, and several kits share the same pump model but contain different components, so the manufacturer part number is the reliable identifier. Where a kit lists a maximum discharge pressure, that figure applies to the pump model it is compatible with, not to the kit as a standalone pressure rating. Buyers working from an existing pump nameplate or a maintenance schedule can use the model number and part number together to select the correct kit.
