Installation
1/4 in. and 6 mm SCO systems have fractional or metric Swagelok tube fittings for all internal system connections. For metric
systems when an R3A series is specified, refer to the supplied data sheet for outlet connection type and size for country/
regional-specific relief valve. For systems with a captured inlet vent, a needle valve will be used with a 1/4 in. NPT female end
connection (illustrated below). For noncaptured inlet vent systems, a bleed valve is used to vent to atmosphere.
•
CAUTION Position the bleed valve so that system fluid is directed away from operating personnel. Always
open bleed valves slowly. Operating personnel must take suitable measures to protect themselves
from exposure to system fluids.
•
CAUTION Do not allow any thread sealant to enter the regulator or fluid stream.
Install the Swagelok tube fittings according to the Tube Fitting Instructions for 1 in. (25 mm) and smaller fittings , MS-12-01.
