These
are usually installed on the more portable or "mobile" end. The type B
can be coupled to a garden hose adapter to backflush plate chillers or
to fill vessels with fresh brewing water. There are probably other good
uses.
Brewhardware's stainless steel
Camlock style disconnects (sometimes called cam and groove) are the best
compromise between cost and function for making and breaking
connections between your vessels, chillers, pumps and hose sets.
Eventually you get tired of pushing tubing onto hose barbs and adjusting
worm gear clamps. These are cheaper than triclovers and all other
stainless steel quick disconnect designs. Best of all, they are milspec
standard around the world so you'll never get stuck with a single
vendor's proprietary disconnect system and have trouble adding on to it
several years down the road.
