Compression fittings are generally intended to be used with soft copper piping. While I have seen them work on rigid copper pipe, though leaks are typical with that application, I would never considered using a brass compression fitting as you have described. The fitting pictured is intended to adapt pex to copper by soldering the fitting pictured into a copper fitting. Typically, plumbers will use a brass/copper stub out where the water valves are installed. Sent from my iPad
You would need to solder part LF4517510 to each end of an LF2500400 manifold in order to connect 3/4" PEX. LF2500400 would fit over the outside, but LF4507510 is the same size as the manifold.
You definitely need to use LF4517510 since it is made to go on the outside of the manifold, which is the same size as 1 inch copper pipe. The other item is designed to go on the inside of a copper fitting, not on the inside of copper pipe. Don't forget something for the other end of the manifold, either another fitting, or a standard 1 inch copper pipe cap.
That is right. Take you time soldering lead free brass must be real clean! Sent from my iPad
Unfortunately the insertion depth is only around 5/8" on the fitting, while a 1/2" copper press generally requires a 3/4" insertion.
No, this fitting must be used in conjunction with an expander tool and pex A tubing.
Did you mean crimp fittings and rings. If you did they take just regular pex fittings. This fitting will not work with anything but an expansion tool which is expensive. It also only works with type a pex.
yes
Yes you can use a sweat adaptor on a shower valve, but solder it only to the hot and cold inlets, and without the cartridge installed. Also do not use them on the shower riser, or the tub spout ports. Use copper tubing for tub and shower ports, as wirsbo restricts the flow causing water to flow out of tub and shower openings at the same time. I learned this the hard way.
Yes, there are other fittings that would be a better choice. But with the proper attention to the shower valve and appropriate support of the valve, it can be sweated to the valve and used with no particular problems.
This part, LF4501010, sweats to copper fittings. It fits inside a copper fitting as copper pipe would. It sounds like you're looking for a copper pipe adapter, which is part LF4511010 in that size.
