Conextlink 5pcs Waterproof IP68 Nylon Firewall Bushing Grommet Cable Gland Joint Adjustable Locknut Protectors for Power Cable (1/0 Gauge, Black) （19001）

I'm doing multiple runs of wielding cable 2/0 from alternatorto batteries, 4 runs. I needed to drill a 1 1/4 inch hole to use this item. Make sure the surface is flat or you won't get a solid seal, also set it in place before running wire threw it its hard to tighten the nut to the firewall with wire running threw it.I would buy again if I need more. These are larger than other 1/0 firewall seal plugs.

Really nice that the feed end can be tightened thus holding the 4 AWG cable instead of just passing through therefor it will not rub. Photo's are just examples, as the work wasn't finalized.

Pleased, the Nylon Cable Glands have worked well for me, in my application had to modify then slightly, and they still proved durable. So far, all good.

The media could not be loaded. Functions great will make water tight seal. Once installed I will post pictures.

These 1/0 bulkhead grommets are heavy duty, which is great, but they're also freaking huge. I am using them with KnuKonceptz Kolossus Flex 1/0 OFC cable, and the nut is nearly bottomed out before the grommet finally tightens around the cable. If my 1/0 cable was any thinner, there's no way these would create a seal around the cable.

I believe some of these reviews are from those who don’t understand some wiring isn’t true to spec in size 😂 cheap brand CCA undersized wire isn’t going to fit what is meant to hold true awg wire. If you have true AWG wire, these are amazing. I’d look into this brands wiring if you’re looking for the best price and spec wire in true tinned OFC.

had to drill through the firewall in my Nissan Juke. got these to run my amp wires. they work great would buy again

Wish oril'eys would carry them
