IRP 3/8 Inch Copper Tube Universal Line Service Valves With Schrader Core – CTE38 (2-Pack?)

If you're working on refrigeration or AC lines, these are handy.

It's a set of IRP copper access tubes—model CTE38.

They're 3/8 inch tubing, and they come with Schrader cores already in 'em.

You braze these into the line, and then you've got a service port to check pressures or add refrigerant.

Made in the USA, brand new.

Universal fit, just cut and braze.

Probably a two-pack?

The description's a bit vague, but they're what you need to add a service valve to a copper line.
