Male Bspp X Female Npt

Description & Features

A straight steel adapter connecting a 3/8" Male BSPP (G 3/8-19) thread on one end to a 1/2" Female NPT (1/2-14 NPTF) thread on the other, this Male BSPP X Female NPT fitting is manufactured by Adaptall for reliable cross-standard thread conversion in hydraulic systems. The straight configuration keeps inline routing clean and direct, with an overall length of 41.4mm and a wrench width of 28.5mm for straightforward installation with standard tooling.

Steel construction suits demanding industrial environments where thread compatibility between British Standard Parallel Pipe and National Pipe Taper connections is required. The NPTF side provides a pressure-tight mechanical seal, making this adapter well suited for hydraulic lines and fluid power circuits where a secure, leak-resistant connection between differing thread standards is necessary.

Question by: Gary J on Sep 21, 2025, 12:46 PM

Will this adapter hold up okay in a hydraulic system running at, say, 2000 PSI?

Steel construction makes this adapter suitable for demanding industrial environments, especially where you need that pressure-tight mechanical seal between BSPP and NPTF threads in hydraulic lines.

Got a piece of equipment running BSPP ports and I need to tie into a half-inch NPT line. This the right adapter to make that work?

Answer by: Customer Support on Apr 19, 2025, 4:51 PM

For that exact situation, yes. One end is a 3/8" Male BSPP (G 3/8-19) and the other is a 1/2" Female NPT (1/2-14 NPTF). So you'd thread the BSPP end into your equipment's port and run your NPT line into the female end. The NPTF thread form on the NPT side is built for a pressure-tight mechanical seal, which makes it a solid choice for hydraulic lines where you can't afford a weeping connection.

got a hose end that’s G 3/8-19 BSPP male, will this let me hook into a 1/2-14 NPTF female port?

Answer by: Customer Support on Apr 15, 2025, 6:57 AM

Function-wise, yes. It is a straight steel adapter with a 3/8 inch Male BSPP (G 3/8-19) on one end and a 1/2 inch Female NPT (1/2-14 NPTF) on the other, so it is meant to bridge those two thread standards in a hydraulic connection.
