b. For metal face seal connectors, assemble connections per standard practice described by
fitting supplier (typically 1/8 turn past finger tight).
c. For compression-type connectors, insert the tube into the fitting until it stops. Tighten the
fitting by applying 1-1/4 turns of nut rotation.
i) For reinstallation, mark the nut and the valve body before disassembly. This will
allow the nut to be returned to the original assembly position. Insert the tube and
attached ferrules into the fitting until fully seated. Rotate the nut until it is returned to
the original assembly position, and tighten slightly beyond marked position.
d. Most valves can be attached to panels or mounting plates using the 10-32 or M5 female
thread mounting holes located in the bottom of the body (valves with M5 mounting holes
will be marked with a “5” on the bottom of the body). Special configurations or multi-
valve blocks may not have mounting holes or may have different size holes. Refer to the
specific data sheet or Technical Bulletin for detailed mounting information.
4. After installation, perform a leak test of all connections and welds per standard industry
practice (reference SEMI standard F1).
