Due to a change in the manufacturers’ process to reduce material in the fittings for cylinders and master valves we will be changing our fitting supplier. The new fittings will be steel and have a better collar for applying pressure to take out hose, a better swivel feature and a rubber washer instead of a metal washer.

Due to this change the thread type in the cylinders and master valves had to be changed. This will make ordering spares a little tricky. All cylinders and master valves that have a “P” stamped in the bottom of it will accommodate the old and new fittings. However the old threads will not accommodate the new fittings.

So it is important to be sure which fittings the customer will need. All cylinders that are sent out previous to Dec 2013 will be old fittings. All new equipment in 2014 will have the new steel fittings. This will also effect the cylinder assemblies and master valve assemblies part numbers as follows:

OLD – AF103

OLD – AF139

NEW – AF103S

NEW – AF139S

NEW – ASM4058S 8” cylinder assembly with Steel QD fittings

NEW – ASM463BS Set up for the Up kiln Arch with Steel QD fittings
