A/C & Heat Diamond Bulkhead Threaded / Push On

Diamond a/c and heater bulkhead fitting.  The bulkhead fitting is great for running a/c and heater hoses through the firewall.  The fittings on the bulkhead are standard a/c fittings: one #6 5/8"-18 and three #10 7/8"-14.  Two of the # 10 fittings are half threads, and half nipples.  The nipples are designed to use hose clamps on the inside of the vehicle where the 5/8" heater hoses connect.  The connections under the hood keep the fittings looking similiar or can be used to step a 5/8" heater hose to a 1/2" heater system.  Straight, 45 and 90 degree heater hose adapter fittings are available on our site, click here.    The bulkhead can be polished or chrome plated with little effort.
