Low-Pressure Press-Connect Stainless Steel Unthreaded Pipe Fittings

- For Use With:
304 Stainless Steel: Air, Ethylene Glycol, Propylene Glycol, Water, Diesel Fuel, Fuel Oil
316 Stainless Steel: Drinking Water, Isopropyl Alcohol, Nitric Acid (10%), Phosphoric Acid (25%), Deionized Water, Anhydrous Ammonia - Maximum Pressure:
304 Stainless Steel: 125 psi @ 72° F
316 Stainless Steel: 200 psi @ 72° F - Specifications Met:
304 Stainless Steel: ASME B31.1, ASME B31.3, ASME B31.9, Uniform Mechanical Code, Uniform Plumbing Code
316 Stainless Steel: ASME B31.1, ASME B31.3, ASME B31.9, NSF/ANSI 61, NSF/ANSI 372, Uniform Mechanical Code, Uniform Plumbing Code - O-Ring Material:
304 Stainless Steel: Fluoroelastomer Rubber
316 Stainless Steel: EPDM Rubber - Pipe Nipples and Pipe: Use Schedule 10, 40 Stainless Steel
- Flanges: Use Class 150 Stainless Steel
Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat. Fittings have an internal stainless steel gripping ring and rubber O-ring that create a seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. These fittings are comparable to Viega MegaPress fittings.
Fittings comply with the Uniform Plumbing Code for plumbing systems and the Uniform Mechanical Code for HVAC and refrigeration. They also meet ANSI/ASME B31 code requirements for use in pressure piping systems.
316 stainless steel fittings stand up to harsh environments with constant exposure to chemical solutions. They meet NSF/ANSI Standard 61 for use with drinking water, and are often found on water and chemical processing lines in corrosive environments.
Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.

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 flange, then wrench-tighten one to two turns.

Easy-Access CPVC Pipe Flanges for Chemicals
- For Use With: Acetic Acid (10%), Calcium Chloride, Deionized Water, Hydrochloric Acid, Phosphoric Acid, Salt Water, Sodium Hydroxide, Sulfuric Acid (80%), Water
- Temperature Range: 32° to 200° F
- Specifications Met: ASTM D1784
- Pipe Nipples and Pipe: Use Schedule 80 CPVC Plastic
The grooved ends on these flanges connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. They are also known as Victaulic flanges. Bolt two same-size flanges together with a gasket (sold separately). Flanges are CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are comparable to Corzan. Flanges meet ASTM D1784 specifications and testing requirements for material quality.
Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

High-Temperature PTFE Pipe Flanges for Chemicals


- For Use With: Deionized Water, Hydrochloric Acid, Solvents
- Temperature Range: -450° to 550° F
- Specifications Met: ASTM D1710
- Pipe Nipples and Pipe: Use Schedule 80 PTFE Plastic
- Fittings: Use Schedule 80 PTFE Plastic
Made of PTFE, these flanges can handle a wider temperature range than any of our other plastic pipe flanges for chemicals. They have the chemical resistance to stand up to acid and solvents. Also known as Pressure Class 150 flanges, they have thick, strong walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so these flanges are commonly used in high-purity processes, such as semiconductor and clean room applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. 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 flange, then wrench-tighten one to two turns. Flanges meet ASTM D1710 specifications and testing requirements for material quality.
Warning: Never use plastic pipe flanges 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.
