Male Bspp X Male Metric

Description & Features

A straight steel adapter connecting a G 3/8-19 male BSPP thread on one end to an M18 x 1.5 male metric thread on the other, the Male BSPP X Male Metric is manufactured by Adaptall for reliable thread conversion in hydraulic systems. With an overall length of 31.5mm and a 22mm CH width for wrench engagement, the adapter is compact and well-suited for installations where space is limited.

Steel construction provides the durability needed for demanding hydraulic applications. The straight profile simplifies routing where a direct in-line connection between BSPP and metric ported components is required.

Will this adapter hold up in a hydraulic system that runs pretty much all day long?

Steel construction provides the durability needed for demanding hydraulic applications, so it should be suitable for continuous use in a hydraulic system.

got a port that’s G 3/8-19 BSPP on one side and M18 x 1.5 on the other. is this the straight adapter for that?

For converting between those two thread types in a straight, in-line connection, this adapter matches a G 3/8-19 male BSPP end to an M18 x 1.5 male metric end.

Question by: Kent M on Dec 31, 2025, 4:30 PM

What exactly is this adapter doing, thread-wise? Like which end goes to what?

Answer by: Customer Support on Jan 2, 2026, 6:38 AM

One end carries a G 3/8-19 male BSPP thread and the other end is an M18 x 1.5 male metric thread. So if you've got a component with a BSPP port and another with a metric port, this piece bridges them in a straight line without any angled routing. Both ends are male, so you'd need female-ported components on each side to make up the connection.
