    Low-Pressure Iron and Steel Threaded Pipe Fittings with Sealant

    To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection. Also known as Pressure Class 125 or 150 fittings. Made of either iron or steel, they’re best in noncorrosive environments. Even with sealant, threaded connections can be taken apart for maintenance and repair.

    Low-Pressure Stainless Steel Threaded Pipe Fittings

    Use these fittings in a low-pressure pipe line.
    External-Square-Drive Plugs
    304 Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    Drain, Waste, and Vent Standard-Wall PVC Pipe Fittings for Water

    These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. Fittings are PVC, which has good corrosion resistance. They meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic 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, flanges, and pipe with compressed air or gas.

    Premium Medium-Pressure Stainless Steel Threaded Pipe Fittings

    Unlike other stainless steel fittings, these are cast in the U.S. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition. All fittings adhere to ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. It’s the highest quality standard for Pressure Class 1000 medium-pressure stainless steel fittings. These stainless steel fittings are more corrosion resistant than steel fittings, and almost as strong.

    Underground Drain, Waste, and Vent PVC Pipe Fittings for Water

    With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings. Made of PVC, they have good strength and corrosion resistance. All meet an ASTM specification and testing requirement for material quality, dimensions, and workmanship.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic 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, flanges, and pipe with compressed air or gas.

    Drain, Waste, and Vent ABS Pipe Fittings for Chemicals

    These Schedule 40 fittings are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Fittings meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product dimensions.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape.

    Unlike other stainless steel fittings, these are cast in the U.S. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition. All fittings except plugs adhere to ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. It’s the highest quality standard for Pressure Class 150 low-pressure stainless steel fittings. They also meet either ASTM A351 or A479 requirements for parts that will be used in pressure systems.

    Flame-Retardant Drain, Waste, and Vent Polypropylene Pipe Fittings for Chemicals

    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.
    Either a clamp connector or electrofusion connector is required to connect grooved ends on adapters to pipe or to another fitting with a grooved end. Clamp connectors can be easily taken apart as needed for maintenance. Grooving tools (sold separately) prepare ungrooved ends for clamping. Electrofusion connectors create a stronger, more permanent connection than clamp connectors. Use electrofusion tools (sold separately) to weld these fittings in place.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.
