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.

High-Purity PVDF Pipe Fittings for Corrosive Chemicals
Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. They won’t accumulate particles and are easy to clean, thanks to their smoothness. Comparable to Kynar, these fittings handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene. You can use them at higher temperatures than CPVC and polypropylene. These fittings meet UL 94 V-0 and FM standards for flame retardance. They’re also FDA compliant for direct contact with food, and they meet ASTM requirements for dimensions and tolerances.
Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion tool with a heater bushing (sold separately) that matches your pipe size.

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 Listed, 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).
Offset tees are also known as sanitary tees and eccentric tees. They have an offset branch so the line can drain. Use them for applications that require frequent cleaning and inspecting.
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.
Plastic Push-to-Connect Tube Fittings for Chemicals
- For Use With: Inch: Alcohol, Hydrochloric Acid, Nitric Acid, Sodium Carbonate, Sulfuric Acid
Metric: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Sodium Carbonate, Sulfuric Acid - Temperature Range: Inch: 0° to 270° F
Metric: 32° to 175° F - Tubing: Use with hard (Durometer 55D-60D) FEP plastic
Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Use these fittings in low-pressure applications.
PVDF fittings offer excellent chemical resistance, and can be used with hydrochloric acid and nitric acid. They withstand temperatures up to 270° F, higher than other push-to-connect fittings for chemicals. They are produced in a clean room and are bagged individually to prevent dirt and moisture from contaminating the inside. PVDF is also known as Kynar.
NPTF (Dryseal) threads are compatible with NPT threads.
Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.
Inline tees are also known as branch tees.
Threaded connections can be taken apart as needed for maintenance and repair.
Right-angle tees are also known as run tees.
Threaded connections can be taken apart as needed for maintenance and repair.
Inline tees are also known as branch tees.

Compression Fittings for Plastic Tubing—Chemicals
- For Use With: PFA Plastic: Hydrochloric Acid, Sulfuric Acid
PTFE Plastic: Alcohol, Ammonia, Benzoic Acid, Bleach, Bromine, Coolant, Fluoboric Acid, Hydrochloric Acid, Hydrofluoric Acid, Nitric Acid, Organic Solvents, Sodium Carbonate, Sulfuric Acid - Temperature Range: PFA Plastic: 0° to 350° F
PTFE Plastic: -40° to 185° F - Tubing: PFA Plastic: Use with hard (Durometer 50D-65D) PFA or PTFE plastic
PTFE Plastic: Use with hard (Durometer 60D) PFA or PTFE plastic
A sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. Fittings that include a gripper sleeve on the tubing create an even tighter seal.
PTFE fittings are highly resistant to most acids, alcohols, detergents, and solvents. They’re made by machining. Their nut is made of PVDF, which is resistant to halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, and organic solvents.
