Sch 40 PVC unions are designed to assemble two pieces of pipe together and will leave the ability to disassemble the pipe with the union ends. Unions are used in systems that may need preventative maintenance or scheduled work within the piping system. Unions are manufactured with socket glue ends, female threaded ends and with one end socket one end threaded. PVC unions meet ASTM D 1784 and ASTM D 2466 industry standards and are suitable for potable water service.

Schedule 40 PVC unions are used to create a secure connection between two lengths of Schedule 40 PVC pipe that can be easily disassembled when needed. PVC union fittings are ideal for pipelines that require maintenance, repair, and modification. Unions allow pipes to be disconnected and reconnected without the need for cutting or complete deconstruction. Sch 40 PVC unions consist of a nut, an end tailpiece, and a union fitting with an internal seal to prevent leaks in the conveyance system under normal pressure ratings. 

Sch 40 PVC Union Sizes and Options

Sch 40 PVC plug fitting sizes range from 3/8" to 6" in diameter for use with the same size Schedule 40 pipe. Connection options include spigot or male threads. Spigot PVC plugs are compatible with socket end pipes and should be installed with primer and cement for a permanent set. Threaded PVC plugs are MPT type with exterior threads compatible with female threaded pipe or fittings. A quality pipe tape should be used when installing threaded plugs. 

Quality and Safety Standards

Schedule 40 PVC plugs are manufactured to meet rigorous industry standards for both quality and safety. The fittings comply with ASTM D2466 which ensures consistent dimensions, material properties, and performance, and ASTM D1784 for the PVC itself and specific property requirements for impact resistance, tensile strength, and heat deflection. Our Sch 40 plugs also meet NSF 14 and 61 standards for potable water applications. These quality and safety standards cover material safety, leak resistance, and pressure capacity to demonstrate the plugs are reliable and non-toxic for designated uses. Our PVC plugs are USA made by reputable manufacturers with internal quality control measures that exceed industry standards for consistent product quality.
