MIL-C-38999 MIL-C-83723 EN2997 ESC10 ESC11

Test after test by major aircraft engine manufacturers have proven the following to be true:

HIRELCO Self-Locking Plugs exceed what others strive to meet! So well, in fact that to date no tough environmental application has been encountered on an aircraft where HIRELCO Plugs do not only exceed military specifications, but moreover, exceed customer expectations.
The unique patented locking mechanism maintains full metal to metal bottoming between plug and receptacle under all vibration conditions.
Friction fretting between plug and receptacle is eliminated, which, in turn, greatly reduces contact fretting.
The locking mechanism is sealed. Nothing gets in or out.
The HIRELCO plug needs no inspection or maintenance in service.
Your sole cost of ownership is the purchase price. The connector will outlast the life of the harness.
