The highest-quality socket-connect fittings available, these meet ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. Also known as Pressure Class 150 fittings, they are designed for low-pressure applications. Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.

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. All of these fittings are made of 304 stainless steel to resist corrosion from frequent exposure to water and fuels. They’re often used for water processing lines, heating and cooling systems, and fuel lines. They are comparable to Viega MegaPress fittings.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat. An internal gripping ring and rubber O-ring create a secure 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 steel fittings are coated in zinc-nickel to resist corrosion, but will rust if frequently exposed to saltwater or harsh chemicals. They are comparable to Viega MegaPress steel fittings.

Fittings meet ASME B31 code requirements for use in pressure piping systems.

Fittings with an EPDM rubber O-ring are often used for water processing lines, fire sprinklers, and heating and cooling systems. EPDM rubber won’t degrade when exposed to water, ethylene glycol, and propylene glycol. These fittings meet UL 213 and FM 1920 standards for use in fire protection systems.

Buna-N rubber O-rings hold up to natural gas, propane, diesel fuel, lubricants, and other oils. Fittings with these O-rings are often used in fuel gas systems and air lines. They meet the ANSI LC4/CSA 6.32 standard for fuel gas systems and comply with the International Fuel Gas Code.

Connect these fittings to Schedule 80 pipe–they have thicker, stronger walls than standard-wall fittings so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

To prevent leaks in threaded connections, apply a sealant to the male threads. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. For metal threads, use PTFE tape. 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.

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.
