This LV Automotive 16mm Extended Red Insulator kit keeps battery terminals covered on compact setups that use a 16mm ring outer diameter. You get 5 covers in the pack, so you can finish a dual battery layout plus a couple of accessory feeds in one job. Each cover handles cable from 8 B&S up to 2 B&S, which lines up with most starter, winch, and charge circuits you will run.

The moulded red body stands out on positive runs and sits only 32mm long, handy when the space between a battery post and bodywork is under 40mm. The bore size and wall thickness suit heavy 2 B&S cable without splitting as you push the lug home. That makes this a smart buy for anyone wiring 12V or 24V gear that cops vibration, dust, and heat in Australian conditions.

Q: Can these insulators be used on both 12V and 24V systems?

Yes, they can be used on both 12V and 24V systems. They are simple plastic covers that fit over ring terminals rather than electrical components that limit voltage. As long as the terminal ring outer diameter is 16mm and the cable size is between 8 B&S and 2 B&S they will fit. They are commonly used on starting, charging and accessory circuits in both system voltages.

Q: Will these covers fit oversized welding cable instead of B&S sizes?

They will only fit correctly if the cable is similar in size to 8 B&S–2 B&S. If the welding cable diameter matches those B&S sizes the bore of the insulator should seat around the insulation. If the cable is significantly larger the cover may split or not slide fully over the crimp barrel. Measuring the outside diameter of your cable before purchase is the safest approach.

Q: Are these insulators suitable for marine battery setups?

Yes, they are suitable for marine battery setups. The covers are non-metallic sleeves that sit over the connection and help reduce accidental contact in confined compartments. They are often used on small boats that run 12V or 24V systems using 8 B&S to 2 B&S cabling. Good practice is to pair them with secure cable support and proper waterproof terminations.

Q: How should I install these over existing ring terminals?

The insulators should be slid onto the cable before crimping the lug. First feed the open end of the insulator over the cable so it sits clear of the stripped conductor. Then crimp the 16mm ring terminal onto the 8 B&S–2 B&S cable. After checking the crimp you can slide the insulator forward so it covers the barrel and seats against the ring. Finally connect the lug to the battery stud and push the cap into place.

These 16mm extended red insulators suit battery terminals with a ring outer diameter of 16mm.

They are suitable for cable sizes from 8 B&S to 2 B&S.

Use them on battery and power distribution terminals in automotive or marine 12V and 24V setups where these cable sizes and terminal dimensions are used.

Push the insulator over the cable and ring terminal after crimping to cover the exposed connection.
