High-Purity Polypropylene Pipe Fittings for Corrosive Chemicals
The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings. These fittings meet NSF/ANSI 61 for use with drinking water, and they’re FDA compliant for direct contact with food. They also meet ASTM requirements for material and performance, and ISO requirements for dimensions.
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.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

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.

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.

- Maximum Temperature: 220° F
- Specifications Met: ASTM D4101, ASTM D635, ASTM F1412, UL 94 V-2
- Compatible with Gravity-Flow Polypropylene Pipe for Corrosive Chemical Waste
Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies. All meet UL and ASTM standards for flame retardance and self-extinguishment in the case of fire. They also meet strict ASTM specifications and testing requirements for material quality and product dimensions. They’re compatible with Orion Blueline No-Hub and Orion Rionfuse chemical waste pipe and pipe fittings.

Chemical-Resistant PVDF Pipe Fittings for Food and Beverage
- For Use With: Beverage, Chlorine, Deionized Water, Food, Hydrochloric Acid, Phosphoric Acid
- Temperature Range: 0° to 240° F
- Specifications Met: FDA Compliant 21 CFR 177.2510, IEC 60695-11-10, NSF/ANSI 61
Made of PVDF, also known as Kynar, these fittings stand up to the harsh chemicals used to clean food processing lines. Unlike other plastic fittings, such as nylon and acetal fittings, they’ll resist degrading when exposed to strong alkali and highly acidic solutions. These fittings are FDA compliant and meet NSF/ANSI 61, so they're safe to make direct contact with food and drinking water. They also won't transfer tastes or odors to your food and beverages. Use them with both hot and cold substances. Since they're made of PVDF, these fittings can stand up to impact. They meet strict IEC standards for flame retardance, so they delay the spread of flames.
Since these fittings are threaded, you can take apart their connections for maintenance and repair. When connecting to another fitting, 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.
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.

37° Flared Fittings for Stainless Steel Tubing

- Tubing: Use with welded or seamless 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Specifications Met: ISO 8434, SAE J514, except fittings with BSPP and BSPT threads meet SAE J514 only
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They withstand high pressure, so they’re often used in hydraulic applications. Made from 316 stainless steel, they resist corrosion from water and chemicals. A complete fitting requires a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
