Schedule 40 pipe has thicker walls than Schedule 10, but not as thick as Schedule 80 pipe. Pipe's exterior includes threading on both connection ends. These connections use PTFE tape to secure seal. Low-pressure (100-299 psi) pipe and nipples connect with fittings. Low-lead pipe is precision machined for leak-free connections between pipe and fittings. The low-lead content is rated for use with drinking water.

Schedule 80 pipe has thicker walls than Schedule 40, but not as thick as Schedule 160 pipe. Pipe's exterior includes threading on both connection ends. These connections use PTFE tape to secure seal. Low-pressure (100-299 psi) pipe and nipples connect with fittings. Bronze, also known as red brass, is a metal alloy of copper and tin. Bronze resists corrosion from saltwater and has higher heat and electric conductivity than most metals.

Instrumentation pipe is precision machined and threaded on both connection ends for leak-free connections between fittings and instruments. Pipe's exterior includes threading on both connection ends. These connections use PTFE tape to secure seal. High-pressure (1000-3000 psi) pipe nipples connect with fittings.
