Tubing Drain Refurbishment Instructions, February 2011 1
Consult Figure 1 for drain terminology
1.) Remove and discard old o-rings.
2.) Clear the OD of the body and ID of the sleeve
of any remaining shear screw fragments.
3.) Clean the drain body and sleeve thoroughly
prior to inspection.
4.) Inspect and gauge the Male (Pin), Female
(Box) EUE threads on the body as well as the
1/4 UNC threads on the sleeve for damage,
and chase if necessary.
5.) Inspect the areas highlighted on the tubing
drain body (see Figure 2).
Note any deformation, gouging or damage to
the o-ring glands (the two grooves directly ad-
jacent the drain port) and the shear screw
groove.
Minor damage to the shear screw groove,
such as burrs at shear locations, can be re-
paired with some light filing. Care must be
taken not to fillet or chamfer any of the groove
edges.
6.) Inspect the sealing surfaces of the tubing drain
sleeve (see Figure 3).
If there are gouges or other marks that would
compromise the seal, the sleeve should not be
reused.
1.) Remove o-rings from Refurbishment Kit package. Note: the o-rings
are different sizes, and are not interchangeable.
2.) Install the larger o-ring in the
gland nearest the Box-end of
the tubing drain.
3.) Install the smaller o-ring in the
gland on the other side of the
drain ports.
DO NOT INSTALL THE O-
RING IN THE SHEAR SCREW
GROOVE.
See Figure 4 for proper o-ring
placement.
1.) Lubricate the o-rings using Castrol MP
grease. However any o-ring lubricant
suitable for use on fluorocarbon (FKM)
seals will be acceptable.
2.) Slide the tubing drain sleeve over the
body, with the shear screw holes to-
ward the pin end of the drain (see Fig-
ure 5).
3.) Press the sleeve into place. There
should be no gap between the sleeve
and the shoulder of the tubing drain
body (see Figure 6).
4.) Install the shear screws in the sleeve in
an alternating star-type pattern using
minimal hand-tight torque. Do not
over-tighten. See Figure 7.
5.) Hydro test the drain up to 50% of acti-
vation pressure to test for leaks.
B.) Install Refurbishment Kit
C.) Reassemble
