Adaptor BPT to NPT Thread Coolant Line 240Z 510

New stainless steel 1/4" BPT to 1/4" NPT adaptor for Datsun 240/510 thermostat housing. The Threads in the side of the water outlet housing are British Pipe & a regular NPT will not fit correctly so this adaptor will fix that. Allows the use of more available barbs, sensors, etc in 1/4" pipe thread. Fitting only. Note that 1/4" pipe thread has an O.D. of about 1/2".
