Question by: Gary M on Sep 10, 2025, 9:19 PM
brass fitting here, male 3/8-24 MPT on one end going into a female hose or tube connection on the other -- that right for this part?
Answer by: Customer Support on Sep 12, 2025, 7:05 PM
that's the correct read on it. One end is a 3/8-24 NPTF male thread, and the other end accepts a hose, line, or tube on the female side with a hex size of 0.813 inches. Brass construction throughout, so it plays well in hydraulic, pneumatic, and instrumentation setups where you need a reliable straight adapter between those two connection types.
