Description

CMP 25301-004-070 Split Union Nut, 2″

The CMP 25301-004-070 Split Union Nut is a precision-engineered plumbing component designed to provide secure, reliable, and service-friendly connections in a wide range of water circulation and fluid-handling systems. Manufactured by CMP (Custom Molded Products), a trusted name in pool, spa, and industrial plumbing solutions, this split union nut reflects the brand’s commitment to durability, compatibility, and long-term performance. Specifically sized for 2-inch union assemblies, this component plays a crucial role in ensuring leak-free connections while allowing easy disassembly for maintenance or system upgrades.

At its core, the split union nut is designed to simplify installation and servicing in tight or hard-to-reach spaces. Unlike traditional solid union nuts that require sliding over pipe ends before assembly, the split design allows the nut to be installed around existing piping without cutting or dismantling the line. This makes the CMP 25301-004-070 particularly valuable in retrofit projects, repair scenarios, and maintenance tasks where minimizing downtime and labor is critical. The two-piece split configuration fits securely around the pipe and mates seamlessly with compatible union bodies, delivering the same holding strength and sealing reliability as a standard union nut.

Constructed from high-quality, chemical-resistant thermoplastic material, the CMP 2″ Split Union Nut is engineered to withstand demanding operating conditions. It resists corrosion, scaling, and degradation caused by prolonged exposure to water, chemicals, and varying temperatures. This makes it well suited for applications such as swimming pool circulation systems, spa equipment, water treatment assemblies, irrigation setups, and light industrial fluid systems. The robust material selection ensures that the nut maintains its structural integrity over time, even in environments where moisture, pressure fluctuations, and chemical exposure are constant.

The internal threading of the CMP 25301-004-070 is precisely molded to ensure smooth engagement with matching union threads. This precision reduces the risk of cross-threading during installation and helps achieve consistent torque when tightening. Proper thread engagement is essential for maintaining a uniform compression on the union’s O-ring or sealing surface, which in turn ensures a dependable, leak-free connection. The nut’s design allows for hand-tightening in most applications, with additional wrench tightening possible if required, without compromising the threads or the overall assembly.

Another key advantage of this split union nut is its role in system maintainability. Pumps, filters, heaters, valves, and other inline components often require periodic removal for cleaning, inspection, or replacement. By using a split union nut, technicians and installers can disconnect equipment quickly without disturbing adjacent pipework. This not only saves time but also reduces the risk of damaging pipes, fittings, or seals during servicing. In commercial or residential pool systems where equipment uptime is important, this ease of access translates directly into lower maintenance costs and faster turnaround.

The CMP 25301-004-070 Split Union Nut is designed with dimensional accuracy to ensure compatibility with standard 2-inch union fittings commonly used in CMP assemblies and other compatible systems. Its consistent sizing helps maintain alignment between connected components, reducing stress on pipes and fittings once installed. Proper alignment is especially important in pressurized systems, where uneven stress can lead to premature wear, leaks, or failure. By maintaining correct positioning, this split union nut contributes to the overall longevity and reliability of the plumbing system.
