This plug has 1" - 14 UNS threads and an o-ring seal for use in a counterbored threaded boss. Recommended counterbore dimensions are 1.155 - 1.165 in diameter by .100 - .110 deep.
The black anodize finish provides excellent protection against most environments. The internal pressure rating is 10 psig maximum.
Recommended installation torque is 30-40 in-lbs.
