Pretty rare now, since CMA moved on to use the three-way combination expansion with one way check valve assemblies. Also available in the less common 3/8" x 3/8" version, part AS_232. Releases at 12 bar. Made of low lead content brass CW510L (OT57), the water flows in (pushes towards) the gasket on the inside.
