High-Temperature PTFE Pipe Fittings for Chemicals
Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They have the chemical resistance to stand up to acid and solvents. Fittings have thick, Schedule 80 walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so these fittings are commonly used in high-purity processes, such as semiconductor and clean room applications. They have a super-smooth interior for unrestricted flow. 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 D1710 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 Flanges 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 D4024
Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges meet ASTM D4024 specifications and testing requirements for product dimensions, performance, and material quality.
To connect flanges to pipe, first sand the inside of the flange 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 flange, applying a layer approximately 1/16” thick. After sealant has been applied, push the flange onto the pipe until it is fully engaged. Make sure you align the bolt holes prior to installing to minimize rotation after the flange is installed. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and flange at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and flange will be ready to use.
Warning: Never use plastic pipe flanges and pipe with compressed air or gas.
