1008A REPLACEMENT PARTS
S tarting in October 2009, the 1008 series valves were replaced with the redesigned 1008A series valves. The differences between the 1008A and the 1008 valve designs are as follows: 1. The bottom plate and bottom plate gasket . The old-style flat faced bottom plate and bottom plate gasket have been replaced with new raised face bottom plate and bottom plate gasket. 2. The shaft seal with shaft seal nut . The old style U-cup and U-cup retaining nut have been replaced by O-rings and O-ring seal nut. The old-style 1008 bottom plates and bottom plate gaskets as well as the old-style 1008 U-cup shaft seal nuts and U-cup
shaft seals are no longer available as replacement parts. The new 1008A parts have been designed to fit into an old-style 1008 valve and are required to repair any old-style 1008 series valve. However it is important to note that the old-style U-cup nuts do not work with the new O-rings. The old bottom plates do not work with the new bottom plate gaskets. If an old-style 1008 bottom plate gasket or shaft seal requires replacement, the new bottom plate and bottom plate gasket or the new shaft seal nut and O-ring seals are required to repair and upgrade the 1008 series to be like the new 1008A series design. The following table indicates the items required to repair and upgrade an old-style 1008 series valve.
