Bulkhead Hose Adapter 5/8″ x 3/4″ Narrow

Aluminium Bulkhead Hose Adapter with 5/8″ male to 3/4″ male fittings. CNC machined from aluminium billet to a high quality surface finish. The hose adapters allow a water tight connection for the heater hose between the interior space and the engine compartment. Some motorsport regulations require a solid connection (rather than rubber grommets) to be used to pass engine coolant through the firewall.

The narrow spaced lock plate is designed with a hexagonal cut out that interlocks with the alloy adapters preventing them from from turning when tightening up the nut on the reverse side. The bulkhead fittings and spacer plate can be polished with little effort.

Kit Includes:

• 2x 5/8″ X 3/4″ Bulkhead Adapters
• 1x Narrow Lock Plate
• 2x M20 Washers
• 2x M20 Locknuts
