CPVC Pipe Fittings for Hot Water
Made of CPVC, these fittings can handle high temperatures. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. They also have good corrosion resistance. These fittings are comparable to Corzan. Some meet ASTM D1784 specifications and testing requirements for material quality.
Fittings for drinking water meet NSF/ANSI Standard 61.
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.
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 regulatory limits on VOCs (Volatile Organic Compounds).

- For Use With: Acetic Acid (10%), Calcium Chloride, Deionized Water, Drinking Water, Hydrochloric Acid (25%), Phosphoric Acid (85%), Salt Water, Sodium Hydroxide (50%), Sulfuric Acid (75%), Water
- Maximum Temperature: 200° F
- Specifications Met: ASTM D1784, NSF/ANSI 61
- Pipe Nipples and Pipe: Use Schedule 80 CPVC Plastic
- Flanges: Use Class 150 CPVC Plastic
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a CPVC primer and cement (also known as solvent weld).
To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant to the male threads. 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.
Inline tees are also known as branch tees.

UV-Resistant Polypropylene Pipe Fittings for Chemicals
Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. 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.
Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.
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.

Fiberglass Pipe Fittings for Corrosive Chemicals
- For Use With: Acetic Acid (75%), Alcohol, Calcium Chloride, Chlorine, Fuel Oil, Gasoline, Hydrochloric Acid (37%), Nitric Acid (10%), Oil, Phosphoric Acid, Salt Water (30%), Sodium Hydroxide (50%), Solvents, Sulfuric Acid (70%), Water
- Temperature Range: 32° to 200° F
- Specifications Met: ASTM D3567
These fittings have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. They are commonly used in metal surface treating applications, plating solution lines, and other chemical process applications. Reinforced with layers of fiberglass, they have better strength and durability than any of our other pipe fittings for chemicals. Fittings meet ASTM D3567 specifications for product dimensions.
To connect fittings to pipe, first sand the inside of the fitting and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8” thick. Repeat this process with the inside of the fitting, applying a layer approximately 1/16” thick. After sealant has been applied, push the fitting onto the pipe until it is fully engaged. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and fitting at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and fitting will be ready to use.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
