With thicker, stronger walls than standard-wall pipe and pipe fittings, these can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Use in high-pressure applications up to 900 psi.

Also known as insert fittings, these have a barbed end that slides into pipe and secures with a clamp. Since you don't have to wait for cement to dry, they're quicker to install than socket-connect fittings. Use in low-pressure applications up to 200 psi.
