Plastic Sink Drains with Collection Trap

Often used in laboratory applications, these drains have a removable collection trap that catches sediment and objects. Traps also block vapors from returning up through the drain.

Drains with slip-joint connection include an adapter tube with an unthreaded male outlet for use as an extension to another slip-joint connection. Trap withstands frost, boiling water, and detergents.

Drain with pipe connection has a semi-clear trap so you can see when it needs to be emptied. Trap withstands harsh chemicals.

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.

Union 270° Bend Adapters, Female Socket Connect × Female Compression Tube

Fittings with a compression end are also known as slip-joint fittings. Insert the tube into the compression end and turn the nut until hand tight. Since you don't have to wait for cement to dry, they are quicker to install than socket-connect fittings.

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.

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