When using an Original-style Gasket, place it into the female
nut whenever possible. No special positioning is needed
because the gasket is self-aligning.
When using a Gasket Retainer Assembly, press the
assembly onto the gland as shown. The retainer assembly
will locate the gasket over the bead and hold it in place. Be
careful not to scratch or nick the bead. Damage to the bead
may cause leakage.
To assemble the connection, hold the male nut or body hex
stationary.
Tighten the female nut finger-tight.
Mark both the female nut and the male nut or body hex.
Hold the male nut or body hex stationary with a backup
wrench. Tighten the female nut 1/8 turn past finger-tight for
316 stainless steel and nickel gaskets or ¼ turn past finger-
tight for copper and aluminum gaskets.
Caution: Excessive overtightening will damage the sealing
beads and possibly cause system leakage.
Disassembly
Removing VCR components in an assembled system
requires no axial clearance. To disassemble a VCR
connection, hold the male nut or body hex stationary with a
backup wrench and loosen the female nut. After removing
the components, be sure to protect the sealing beads with
protective caps or Gasket Retainer Assemblies.
Retightening
To maintain system reliability, install a new Original-style Gasket or Gasket Retainer Assembly
on each remake. Simply follow the previously described assembly instructions.
