Oddball O-Ring Gland Design
Oddball O-Ring Gland Design
(OP)
Hello Forum,
I'm reverse engineering a brass water fitting in a low pressure application. On one side there is a face/flange seal with an O-Ring groove that matches traditional O-Ring gland dimensions. The other side has a radial O-Ring seal with 2 grooves for 2 O-Rings. Those grooves do not match any one set of standard O-Ring gland dimensions per Machinery's Handbook etc.
On my part the width meausures .17" and the depth .12"
The width matches the recommended width for a 3/32" thick O-Ring with one backup ring
However the depth matches the recommended depth for a 1/8" thick O-Ring in a dynamic application.
The water elbow mounts to a very large diesel engine so I suppose the application could be considered dynamic.
Anyone know of any other (free) sources for this type of information?
thanks,

Absent the actual seals, I'd guess that maybe the radial o-ring energizes a TFE slipper, which would account for the extra depth.
