Is PEX measured inside or outside?

Is PEX measured inside or outside?

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. This is why push fittings can be used with all of these pipes.

What is the inside diameter of 1/2 PEX?

3) 5/8 in. tubing is better than 1/2 in. tubing.

PEX Tubing Size Information
Nominal ID OD Avg. ID
1/2″ 0.625 0.475
5/8″ 0.750 0.574
3/4″ 0.875 0.681

What is the inside diameter of 1-inch PEX?

PEX Tubing Size Chart

PEX Tubing size/CTS nominal OD or Outside Diameter Volume gal/100ft
1/2″ 0.625″ 0.92
5/8″ 0.750″ 1.34
3/4″ 0.875″ 1.83
1″ 1.125″ 3.03

Is 3/4 PEX big enough?

In general, the greater the distance from the manifold to the fixture, the wider the PEX tubing should be. A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line.

Which is smaller 3 / 4 PEx or 1 / 2 copper?

PEX fittings go INSIDE the pipe. They are therefore smaller in diameter) A 3/4 PEX fitting is equaly wide as a 1/2 copper fitting – this reduces the water flow. Does that mean that when I replace 1/2 in copper (example for a shower) I should use 3/4 PEX?

What are the dimensions of PEX tubing dimensions?

* Numbers are approximate as per ASTM requirements. 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).

How big of a PEX do I need for my main water line?

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.

How are PEX fittings different from copper fittings?

Pex fittings go INSIDE the pipe. They are therefore smaller in diameter) A 3/4 pex fitting is equaly wide as a 1/2 copper fitting – this reduces the water flow. Does that mean that when I replace 1/2 in copper (example for a shower) I should use 3/4 pex?
