Schedule 40 PVC couplings are pipe connector fittings used in plumbing systems to join two lengths of PVC pipe together. PVC couplings are designed to provide a secure, leak proof connection for fluid transport without the risk of contamination or leakage. Widely used across residential, commercial, and industrial applications, Schedule 40 PVC couplings are essential for plumbing networks being built from plain end Sch 40 PVC pipe. 

Sch 40 PVC Coupling Sizes and Options

Sch 40 PVC coupling fittings come in various sizes and options to meet each plumbing system and setup requirements. Online Sch 40 couplings range in size from 1/2 inch to 12 inches. Large diameter PVC couplings up to 24 inches in size are available on quote request. Schedule 40 PVC coupling connection options include socket and FPT threaded ends. 

Coupling types include standard, reducing, and nested fitting styles. Coupling reducers allow the diameter of a PVC line to be made smaller to connect different sized pipes or give an installer control over flow rate and pressure within the piping system. Nested coupler fittings are designed to “nest” over the same size diameter Sch 40 PVC pipe or inside the next size larger pipe. Nested couplings remove the need to purchase a larger size coupling to fit the pipe needed by the project.

Quality and Safety Standards

Our Schedule 40 PVC coupling fittings are manufactured, tested, and certified to meet current industry standards for quality, health, and safety. Each pipe coupling meets ASTM D 1784 and ASTM D 2466 standards that oversee the technical specifications on the fitting’s physical properties and characteristics. Our PVC couplings are NSF approved for potable water handling for use in domestic and commercial distribution applications.

Applications and Uses

PVC couplings are used across industries and work applications that require multiple pipe lengths to be joined together to form a connected pipe network. Common use applications include water distribution and treatment, pool and spa installation, irrigation, manufacturing, industrial, and chemical handling due to their chemical resistance, long service life, and ease of installation. Schedule 40 PVC couplings are a key part of longer length and/or intricate plumbing systems. PVC couplings are frequently used by plumbers, construction experts, engineers, contractors, and DIY enthusiasts for their projects.
