REASSEMBLE:
Use all the new seals provided and lubricate lightly with an oil
compatible with your system / process during assembly. Replace
pins, springs, balls and handle with new parts as provided in the
rebuild kit.
1) Replace body o-ring with new urethane o-ring.
Lubricate.
2) Lube all eight holes on body with Vaseline. Install
all eight new balls. Once all the balls are in place,
push the body all the way into the sleeve.
3) Pick up the assembly and push the
sleeve back to expose the snap ring
groove. Insert the new snap ring into its
groove.
4) Replace the new main seal and the new Teflon ring
on the piston.
5) Place the piston and new large spring into the main body assembly.
Add the new handle and insert the new handle pins.

OF HANDLE MATCHES TO THICK SIDE OF BODY TAB AS SHOWN. (No
special orientation on 3/8” size.)
6) Lubricate the poppet o-ring and place it on the poppet. Then slide on
poppet back. Place new poppet spring on top of poppet.
7) Replace the o-ring on the brass back piston. Use a drop of LocTite 242
on the threads and assemble the two piston halves. Tighten using a
spanner wrench and torque wrench to 15 ft-lbs.
