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.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
For technical drawings and 3-D models, click on a part number.
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
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. Made of PVC, they have good strength and corrosion resistance. All meet an ASTM specification and testing requirement for material quality, dimensions, and workmanship. Threaded connections can be taken apart as needed for maintenance and repair.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Gravity-Flow Polypropylene Pipe Fittings for Corrosive Chemical Waste
- For Use With: Deionized Water, Hydrochloric Acid, Oil, Phosphoric Acid, Salt Water, Solvents
- Maximum Temperature: 220° F
- Specifications Met: ASTM D4101, ASTM D635, ASTM F1412, UL 94 V-2
- Compatible with Gravity-Flow Polypropylene Pipe for Corrosive Chemical Waste
Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies. All meet UL and ASTM standards for flame retardance and self-extinguishment in the case of fire. They also meet strict ASTM specifications and testing requirements for material quality and product dimensions. They’re compatible with Orion Blueline No-Hub and Orion Rionfuse chemical waste pipe and pipe fittings.

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.
