J599HR plugs with black composite coupling nuts

J599HR High-Vibration 38999 Series III-Type Plugs

400 g shock · 1.5 g²/Hz random vibration · 1000 mating cycles

J599HR is a shielded plug for severe vibration and shock. It mates with our standard J599 Series III receptacles and keeps the triple-start thread, but a composite double-locking anti-decoupling coupling nut holds it without lock wire. Shock rating is 400 g versus 300 g for the standard plug, and the plug is up to 42 % lighter in stainless steel.

Frequently asked questions

Does J599HR mate with standard J599 Series III receptacles?

Yes — J599HR is a plug designed for our J599 Series III receptacles and uses the same insert arrangements. For receptacles from other makers, send the part number and we will propose samples for your mating test.

Why is no lock wire needed?

The composite coupling nut has a double-locking anti-decoupling mechanism that holds under the rated vibration and shock, so installation and maintenance are faster.
