Grease Traps

Steel

Plastic

Often used in restaurants, these grease interceptors remove and retain grease from waste water to prevent blockages inside the plumbing system.

Steel traps use a no-hub pipe coupling (not included) to connect to pipe.

Plastic traps offer more corrosion resistance than steel traps.

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.

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.

Drain, Waste, and Vent ABS Pipe Fittings for Chemicals

For Use With: Sodium Hydroxide
Max. Temperature: 180° F
Specifications Met: ASTM D2661, ASTM D3311, ASTM D3965, ASTM F1498
Pipe Nipples and Pipe: Use Schedule 40 ABS Plastic
Flanges: Use Schedule 40 ABS Plastic

These Schedule 40 fittings are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Fittings meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product dimensions.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with ABS cement (also known as solvent weld).

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

Gravity-Flow CPVC Pipe Fittings for Corrosive Chemical Waste

For Use With: Hydrochloric Acid, Nitric Acid, Salt Water, Sulfuric Acid
Temperature Range: 40° to 200° F
Specifications Met: ASTM F2618, IAPMO Certified, NSF/ANSI 14, UL 94 V-0

Made of CPVC, these fittings have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances. They meet NSF/ANSI 14 requirements for use in corrosive waste gravity-flow systems. Fittings are comparable to Corzan. They meet UL 94 V-0 for flame retardance and ASTM F2618 specifications and testing requirements for material quality. They are IAPMO certified to comply with the International Association for Plumbing and Mechanical Officials product performance standards and the Uniform Plumbing Code (UPC) for installation and repair of plumbing systems.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a CPVC primer and cement (also known as solvent weld).

270° bend fittings are also known as P-traps. They separate into three pieces, so you can access your line.
