c. GASKETS are used on some inlet connectors. If so, CONCOA includes
gaskets made of a material that is compatible with gases typically
used with the inlet connection. However, please note that the user is
responsible for ensuring that the gasket material is compatible with the
type of gas being used. Be sure the gasket is in good shape. Do not
over-tighten to avoid squashing the gasket into the gas line. You may
want to order an extra supply of these gaskets from your gas supplier.
d. Never use oil or grease on regulator or cylinder fittings, as you may
contaminate pure gases, or create a fire hazard.
1.3 Close the regulator by turning the pressure control knob, or handle,
counterclockwise. As the control knob is closed, turning should become easier.
1.4 Shut the regulator outlet valve (if supplied) by turning the knob on the valve
clockwise.
1.5 Observing the following procedures; make connections from the regulator
outlet to your downstream equipment.
a. BE SURE TO CONSIDER ALL FACTORS WHEN SELECTING
MATERIALS. For example, if you have both high pressure and corrosive
service, select material that is suitable for both.
b. Do not use oil or grease on fittings, especially not on oxidizing gas
service equipment.
c. Be sure that all fittings are secure and leak tight. PTFE tape must
be used on NPT threads to ensure a gas tight seal. Avoid impinging
on the gas stream. On stainless steel connections, PTFE tape
also helps to prevent the connections from galling together when
tightening or loosening. Follow the rules below when using PTFE tape:
Before applying PTFE tape, inspect the NPT threads, and, if necessary,
clean the fitting to remove any dirt or thread sealant that remains on the
