    Default 1/2" compression to 1/2" compression shutoff

    I've been looking for a couple of 1/2" compression to 1/2" compression shutoff (chrome preferably) valves to feed a hot water recirculator. Brasscraft makes them, but nobody seems to stock them. Part # KTCR34C. Anybody got a source? I've spent over an hour searching on the web and stopped at 3 plumbing supply houses, no luck.

    Default tubes

    Are sure you want 1/2" compression. Most of the recirculators have a 1/2" ips size connection and you use a 1/2" ips x 1/2" ips to connect it to the faucet.

    The recirculator I have (RedyTemp) uses 1/2" connectors on each of 4 connectors. Two go directly to the shutoffs, and the other two go to the faucets. I have 1/2" to 3/8" hoses to go to the faucets. It came with 1/2" to 1/2" hoses to go to the shutoffs, but I can't find any compatible shutoffs. The supply is PEX. I have the stainless steel ferrule to use a compression fitting on the shutoff, but can only find 1/2"x3/8" valves. It would probably work with using the 3/8" shutoffs readily available, but I was looking to minimize the restriction for maximum efficiency.

    After taking a close look at the supplied hoses, it doesn't seem like it would matter if the shut-off was 3/8 or 1/2", as the diameter of the hose on those that have 1/2" fittings is the same as those with 3/8". So, thanks anyways...guess I should have looked at the internal dimensions of the tubing before trying to figure this out. Just means that I need to buy two more hoses to complete this installation since I can't use those supplied.

    It appears that you may be some what confused as to the installation procedures. No connections or disconnections of the shut off valves is required. Simply disconnect your current "faucet end" of your current supply line and connect it to the RedyTemp's "industry standard" connection points. Then with the two "supplied flexlines" which came with your RedyTemp, connect one end to your "faucet" connections which previously disconnected and connect the other end of the supplied hose to the RedyTemp. It doesn't get any easier and should take just a few minutes to disconnect and reconnect the flexlines.
