TCH Pump connectors isolate vibration and harmonics, compensate for misalignment, eliminate piping stress and extend the life of pumps and piping systems. Fabricated from 1” – 4” bronze hose or 1” – 24” stainless steel hose surrounded with a heavy-duty woven wire braid, our pump connectors are available in a variety of standard stock sizes or can be custom fabricated to fit your needs. End fittings have a range of materials including copper, carbon steel, stainless steel and style options, weld, sweat, flange, groove, male NPT, or customer specified. Reducing pump connectors are also available.
TCH V, U, and Dog Leg seismic expansion joints are constructed to maintain flexibility under pressure caused by thermal pipe expansion and compression, random motion, or seismic activity. They are capable of 6 planes of motion along the X, Y, and Z axis.
Rubber Expansion Joints
TCH rubber expansion joints isolate vibration and harmonics, compensate for misalignment, and piping system thermal expansion and contraction. Stock I.D.’s 1”-24” molded and spool type, single and double sphere, and female union. Concentric and eccentric rubber expansion joints, including standard carbon steel end fittings with 150# and 300# stainless flanges available. Stock material elastomers are available include EPDM, Nitrile, Neoprene, and Butyl. EPDM is acceptable for Lead Free.
Lead-Free Flex Connectors
TCH Lead-Free Flex™ straight assemblies isolate vibration, allow offset, eliminate pressure stress, and extend service life. Our Lead-Free Flex™ seismic V and U connectors offer protection against any unpredictable seismic or thermal expansion or compression movement. Assemblies are stainless steel hoses and braid with stainless and carbon steel end fittings, ½” I.D.-12” I.D. are available.
