What is the wall thickness of PEX pipe?

Overview. PEX pipe is manufactured to be a copper tube size (CTS) pipe with a wall thickness conforming to a standard dimension ratio of 9 (SDR9).

How big is a standard PEX plumbing pipe?

PEX Diameter. When you’re buying PEX, the important number is the “nominal” size. This construction standard indicates the pipe is compatible with fittings of the same size. The flexible tubing comes in rolls of 50 feet up to 1,000 feet. PEX tubes range in diameter from 3/8-inch to 1-inch for residential applications.

What’s the difference between CPVC and PEX pipe?

Same data applies both to oxygen barrier and non-barrier PEX. Notes: PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). OD of PEX, copper and CPVC pipe with the same size (CTS) is the same.

What’s the minimum bending distance for PEX pipe?

Over-bending the PEX pipe, deforms its’ round shape, restricts flow and over-stresses the pipe. Note: minimum bending diameter only refers to the 90-degree and 180-degree (U-shaped) bends. Parallel runs of pipe can be spaced as close as necessary.

What’s the difference between copper and PEX tubing?

Dimensional data is subject to manufacturing tolerances and may vary by brand. Same data applies both to oxygen barrier and non-barrier PEX. PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). OD of PEX, copper and CPVC pipe with the same size (CTS) is the same.

What is the inside diameter of PEX tubing?

PEX tubes range in diameter from 3/8-inch to 1-inch for residential applications. For adequate water flow, it’s a good idea to install 1/2-inch or 3/4-inch PEX for your main lines. The standard when replacing old water supply lines with PEX is to use the same size.

Can I use PEX for air lines?

FAQs (Frequently Asked Questions) Can PEX pipe be used for compressed air? Yeah, the right kind of PEX pipe (PEX-AL-PEX).

What’s the maximum pressure for a PEX pipe?

Exceptions are nominal sizes 1/2″ and below. 3 times the maximum working pressure or a minimum of 40 psi, but no greater than 100 psi. 1.5 times the maximum working pressure but no greater than pipe’s pressure rating at given temperature. Maximum working pressure indicates highest anticipated operating pressure.

What’s the difference between PEX A, B and C?

There are three common types of PEX: PEX-A, PEX-B and PEX-C. There is a widespread misperception that the letters refer to grades of quality and that PEX-A is better than PEX-B which is superior to PEX-C.
