All prices are for 1 Coupler Bulkhead
 
G10 fiberglass Coupler Bulkheads are precision cut to match Mach 1 tubing, but will work for other manufacturer's tubing (may require light sanding). Each bulkhead has a small mark in the middle to identify true center.
 
These Coupler Bulkheads sit inside the coupler.
