need a locknut for a bulkhead fitting, is this one the female G 1/2-14 BSPP thread?
Answer by: Customer Support on Oct 18, 2025, 2:17 PM
For fitment, this locknut is threaded female G 1/2 - 14 BSPP and sized for 1/2 inch BSPP bulkhead style connections.

What size thread we talking on this locknut, and is it a male or female connection?
Answer by: Customer Support on Aug 20, 2025, 6:57 AM
Female G 1/2 - 14 BSPP thread on this one. So you'd be threading it onto a male BSPP fitting or port. That's a pretty common size in hydraulic bulkhead setups, and the 1/2 inch size keeps it in a range that works across a lot of standard configurations.
