Alloy Bulkhead Water Hose Adapter 16mm to 16mm (5/8"-5/8")

16mm to 16mm Bulkhead Hose Adapter
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 designed with a hexagonal cut out that interlocks with the alloy adapters preventing them from turning when tightening up the nut on the reverse side.

The bulkhead fittings and spacer plate can be polished
