Pentair Black High Pressure Pump Nut

Pentair Black High-Pressure Pump and Slide Valve Union Nut (270141Z / 270141)

The Pentair Black High-Pressure Pump Nut (Product #: 270141Z / 270141) is a rugged, factory-original OEM replacement union component designed to establish a secure, leak-free physical connection within demanding high-pressure pool and spa plumbing loops. Engineered specifically for standard 1.5-inch buttress-threaded fluid interfaces, this heavy-duty retaining collar is universally compatible across an array of premium Pentair and Sta-Rite® equipment, including the SuperFlo®, SuperFlo VS/VST, and SuperMax® variable speed pump lines, as well as Pentair side-mount push-pull (slide) valve assemblies. Injection-molded from a high-density, impact-resistant engineering polymer, the component provides absolute protection against corrosive pool chemicals like high chlorine concentrations, prevents scale and mineral encrustation, and is infused with advanced UV stabilizers to prevent structural brittleness or cracking under constant outdoor weathering and extreme pump room heat. Featuring deep, molded exterior ridges to optimize manual hand-tightening torque during installation, it allows technicians and homeowners to smoothly compress internal sealing o-rings to form an absolute hydraulic seal without stripping the threads or requiring specialized plumbing tools. By absorbing the continuous high-frequency vibrations, hydraulic surges, and backpressure generated by high-performance circulation systems operating up to a maximum continuous baseline of 50 PSI, this nut prevents critical pressure-side water weeping and catastrophic suction-side air induction. The physical weight of this single Pentair Black High-Pressure Pump Union Nut is exceptionally light at approximately 0.18 pounds (roughly 2.88 ounces, with a packaged shipping weight of approximately 0.25 pounds), providing pool professionals and residential managers with an incredibly strong, featherweight, and indispensable hardware element for pristine aquatic circulation systems.
