How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Recessed

Raised

Close off your drain cleanout pipe with these threaded plugs. Note: If you do not know your pipe size, measure the OD of your existing cleanout plug or the ID of your cleanout fitting and match to the value listed.

Aboveground Standard-Wall PVC Pipe Fittings for Drain, Waste, and Vent

For Use With: Water
Max. Temperature: 140° F
Specifications Met: ASTM D1784, ASTM D2665
Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
Flanges: Use Schedule 40 PVC Plastic

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. Fittings are PVC, which has good corrosion resistance. They meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

Plugs with External Square Drive, Male Threaded Pipe

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Underground PVC Pipe Fittings for Drain, Waste, and Vent

For Use With: Water
Max. Temperature: 140° F
Specifications Met: ASTM D2729, ASTM D3034

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings. Fittings are PVC, which has good corrosion resistance. Fittings meet ASTM D2729 and ASTM D3034 specifications and testing requirements for material quality.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Quick-Open Duct Access Panels

The panels open and close by turning the knobs. Also known as cleanouts, panels cover cutouts in duct to provide access for inspection and cleaning. They’re made of galvanized steel for good corrosion resistance. All have a gasket to create a tight seal. Use the included template to make the cutout.

Style D panels have an observation view port that lets you quickly see if dust or debris is blocking the airflow in your duct without having to open the panel.
