Comments about JMF 1/4in Compression Cap (4503520):

Ace Hardware review for a 1/4 inch compression cap:

As with any compression fitting, this cap requires a compression sleeve ("ferrule" or "olive"), which is deformed into a tight seal by compression between the threaded components.

To cap the 1/4 inch compression outlet of a saddle valve, insert a 1/4 inch metal compression sleeve into the back of the 1/4 inch compression cap, and then carefully screw the compression cap onto the outlet of the saddle valve.

Hand tighten, and then use a wrench to turn the compression cap 1/4 turn more. If the compression cap leaks after a while, then tighten the cap slightly; repeat this process until the cap no longer leaks.
