CALBOND Straight Union - Conduit to Conduit: Steel, 4 in Trade Size

A CALBOND straight union connects two conduit sections end-to-end in a 4 in trade size. Its female-to-female FNPT threads allow secure, leak-resistant joints in industrial electrical systems. The urethane coating adds corrosion resistance, making it suitable for harsh environments like chemical plants or wastewater facilities.

The CALBOND PV4000UNF1005 is a 4 in trade size straight union with 4 in FNPT x 4 in FNPT female connections. It is made of steel with a urethane-coated finish for corrosion protection. The female-to-female configuration joins two male-threaded conduit ends directly.

3G Electric supplies the CALBOND straight union PV4000UNF1005 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source genuine parts across 14 departments, including electrical and conduit fittings.

Apply a suitable thread sealant to the male conduit ends. Hand-tighten the union onto both conduits, then use a wrench for final tightening—avoid over-torquing to prevent damage. The urethane coating protects against corrosion, but ensure threads are clean before assembly for a reliable seal.
