In use, the CGA Tailpiece couples to the fill connection on the container being filled. The
Relief Valve vents pressure over 350 psig (24 bar/2413 kPa) that builds up in the fill line
due to trapped liquid. The Dump Valve is used to allow the operator to blow-don the
receiving container during a pump fill, or to relieve residual pressure from expanding liquid
trapped in the line before disconnecting the fill line.
Fill kits are available with different combinations of hose length and fittings for a specific
gas service. The following chart identifies the available transfer hoses and fill tee assem-
blies.
