Medium-Strength Steel

Image of Product. Front orientation. Threaded Rods. Threaded Rods.

With tensile strengths from 110,000 psi to 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also medium-strength steel.

Corrosion-Resistant PTFE-Coated Steel—A PTFE coating protects the steel from corrosion and pitting when exposed to chemicals, such as those found in cleaners and sanitizers. The coating is also slippery to thread on smoothly.

Plastic

All of these rods are lightweight, nonconductive, and naturally rust resistant. However, they are not as strong as metal or composite rods.

High-Temperature Chemical-Resistant PTFE—The most chemical-resistant plastic rods we offer, these stand up to the widest range of harsh acids, bases, solvents, and corrosive cleaners. They also keep their shape and strength at higher temperatures than most plastics. More slippery than nylon 6/6, these rods thread on even more smoothly.

High-Temperature PTFE Pipe Nipples and Pipe for Harsh Chemicals

This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It has the chemical resistance to stand up to acid and solvents. Also known as Schedule 80 pipe, it has thick walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so this pipe is commonly used in high-purity processes, such as semiconductor and clean room applications. It has a super-smooth interior for unrestricted flow. Pipe meets ASTM D1710 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.

Pipe—Fully Threaded

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Threaded Rod and Hex Nut Kits for Pipe Flanges

These kits include the rods and nuts you need to connect standard-size pipe flanges. Their heavy duty material and construction keep tanks, valves, and flanges tightly sealed under heavy pressure. With a 10% wider profile than standard hex nuts, these hex nuts spread force over a larger area and can handle extra torque during installation. The rods are fully threaded to distribute and absorb high levels of clamping force. To ensure your pipe flange connection is tight, add a pipe flange gasket to your installation. These rods and nuts meet a number of rigorous industry specifications for high-pressure performance, high-temperature performance, and dimensional requirements.

Medium-Strength Steel

With a tensile strength of 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods.
