Question by: Ralph M on Nov 16, 2025, 4:05 PM
Got a panel I need to run a hydraulic line through, does this fitting come with everything needed to lock it in place, or do I need to source a nut separate?
Answer by: Customer Support on Nov 17, 2025, 5:21 PM
The locknut is included with this fitting, so you won't need to track down a separate hardware piece. The bulkhead design lets you pass the fitting through a panel cutout, then use the locknut to clamp it securely in place from the other side. Brennan Industries built it as a complete assembly for that reason, no guesswork on what hardware pairs with it.
