Kyle,

Good Evening. Okay, here's an option that will result in a clean, neat installation, that will provide a watertight bulkhead penetration. It involves only three bronze fittings, some pipe sealant and a couple of nice fillets.

Obtain (1) one bronze pipe coupler
Obtain (2) two bronze pipe-to-hose fittings.

Install the coupler in the bulkhead by milling a hole to receive the coupler. Center the coupler and epoxy in place using nice fillets. Then insert a pipe to hose fitting into each end and there you have it. The nice thing about this option is pipe-to-hose fittings have NPT threads, just like the coupler. Also, pipe-to-hose fittings can be either straight, 90 degree or 45 degree. This may assist in where (the direction) you'll be routing the hose.

Bronze couplers are readily available from Hamilton Marine and Jamestown Distributors. Groco Marine produces an assortment of bronze pipe-to-hose fittings that are distributed by various suppliers.

Hope this helps.
