Installing O-rings Section 9.4
If any O-ring is not installed properly, there is a good chance the connection will leak. The way
to install an O-ring depends upon the actual connection itself.
There are two main types of O-ring connections:
#1- Connections that do NOT have a O-ring groove on the part connections.
#2- Connections that have an actual groove for the O-ring on part connections.
When installing the O-rings on connections that do NOT have an O-ring groove (#1), the pro-
cedure is as follows:
-Inspect the O-ring for any nicks or cuts. If any are found, replace the O-ring.
-Use food grade silicone grease to lightly coat the O-ring and all surfaces the O-ring will con-
tact (both the male & female surfaces).
-Install the O-ring on the MALE connection & ensure that the O-ring is not twisted.
-Install all other required parts and slide the connection together.
Pictured below is a diagram reflecting example #1.
Pictured below and to the right is a diagram reflecting example #2.
In this situation, there is a groove designed into the con-
nection for the O-ring to be seated into place.
Installation procedure is as follows:
-Inspect the O-ring for any nicks or cuts. If any are found,
replace the O-ring.
-Use food grade silicone grease to lightly coat the O-ring
and all surfaces O-ring will contact (both the male & female surfaces).
-Install the O-ring into the appropriate groove on the connection.
-Ensuring the O-ring is not twisted, slide the connection together.
