Description
The Pentair 2-Inch Slip Half Union 42001-0402 is a factory-spec replacement set built for Sta-Rite Max-E-Therm pool and spa heaters. Packaged with two slip unions, two locking nuts, two couplers, and two O-rings, this kit supplies every component required to establish a firm, drip-proof bond between your heater and the surrounding plumbing. The union design enables quick disconnection and reconnection of the heater during servicing, component swaps, or full replacements, cutting labor time and simplifying the entire maintenance process. Manufactured to genuine Pentair specifications, these unions are formulated to stand up against pool treatment chemicals, hydraulic pressure, and repeated assembly cycles without losing their seal. Keeping these connections solid and intact helps preserve heater longevity and ensures your Max-E-Therm unit runs with consistent safety and efficiency.
