Flame-Retardant PVDF Pipe Fittings for Chemicals
- For Use With: Chlorine, Salt Water, Solvents
- Temperature Range: 40° to 280° F
- Specifications Met: ASTM D3222, UL 94 V-0
- Pipe Nipples and Pipe: Use Schedule 80 PVDF Plastic
- Flanges: Use Class 150 PVDF Plastic
These fittings meet UL 94 V-0 for flame retardance, so they delay the spread of flames to valuable equipment. They are made of PVDF (polyvinylidene fluoride), which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Schedule 80 fittings, they have thick walls for heavy duty chemical processing applications. When connecting to pipe, 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. Fittings meet ASTM D3222 specifications and testing requirements for material quality.
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.
