Yor-Lok Fittings for Stainless Steel Tubing

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
316 stainless steel fittings have excellent corrosion resistance.

Standard-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 40 plastic pipe–they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.
Fittings for drinking water meet NSF/ANSI Standard 61.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Fittings that meet ASTM D1784, ASTM D1785, and ASTM D4066 adhere to specifications and testing requirements for material quality.
Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Saddle-tap tee adapters allow you to create additional outlets and connections in metal or plastic pipe. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole so the gasket and lip are fully engaged and secure with the included nuts, bolts, and washers.

- 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.

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.

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