Assembly Instructions
General
•
All o-rings must be lubricated with a small amount of silicone grease.
•
A small amount of removable thread locker should be applied to the set screw (19).
•
Assemble the air section and fluid section separately prior to connecting the
assemblies.
Air Section
1.
Mount one 007 Buna o-ring (14) on the end (F) of the micrometer (11) and slide it
up to the threads.
2.
Thread the micrometer (11) into the upper air body (10) hand tight.
3.
Holding the collar (E) of the micrometer (11) turn the dial (C) counter-clockwise
until the number 5 can be seen on the gauge (D).
4.
Using pliers grab the gauge (D) section of the micrometer and turn clockwise to
snug it onto the upper air body (10).
5.
Use a 1/16” Allen key to assemble the set screw (20) into the upper air section
(10) securing the micrometer (11) in place.
6.
Mount one 014 Buna o-ring (13) on the end of the upper air body (10).
7.
Drop the needle (3) into the piston (9) and assemble with the set screw (19) using
an adjustable wrench and 5/64” Allen key to tighten.
8.
Mount the 014 Buna o-ring (13) onto the piston (9).
9.
Apply a small amount of silicone grease to the inside of the lower air body (8)
then drop in the piston and needle assembly.
10.
Mount the 004 Buna o-ring (15) on the end of the needle and slide it down into
the groove in the end of the lower air body (8).
11.
Slide the end cap (7) onto the needle up to the lower air body (8), place the spring
(18) on top of the piston (9), and assemble the two air bodies using two machine
screws (21) tightening with a 3/32” Allen key. Note: Be sure the air holes are
lined up on the same face.
Fluid Section
1.
Drop the packing (5) into the fluid section (4), and screw in the packing nut (6)
but leave finger tight until assembled with the air section.
2.
Mount the 006 Kalrez o-ring (16) on the seat (2) and push the seat into the bottom
of the fluid section (4). When inserting the seat, work the o-ring into the fluid
body with finger to prevent shearing of the edge of the o-ring.
3.
Thread the nozzle adapter (1) onto the fluid body (4) and tighten with an
adjustable wrench.
4.
Drop the nozzle (17) into the bottom groove of the nozzle lock nut (12) and thread
the assembly onto the nozzle adapter (1).
