Review on 🔧 Dewhel Brass 1/8 NPT Female to 1/8 BSPT Male Thread Adapter: Ideal Gauge Sensor Sender Reducer by Amador Buckenmeyer

This adapter did not work as received for me as the male thread would not begin to thread into the 1/8 BSPT female thread. Careful inspection and measurement with a caliper showed that the male threads were not damaged, being parallel threads rather than British tapered tubing. I had to rethread the male threads with a 1/8 BSPT die, after that it worked fine. The female end was true 1/8 NPT. Several other reviewers noted that the threads may not be correct or that the product is in fact BSPP which requires compatible female threads and a sealing washer.
