Din X Mbspp Es Seal

Description & Features

A straight steel adapter connecting a DIN tube end to a male BSPP port, this Din X Mbspp Es Seal is designed for hydraulic line assemblies where metric tube connections must transition to British Standard parallel thread fittings. The DIN side features an M52 x 2.0 thread with an L42 tube designation, while the BSPP side carries a G 1-1/4 - 11 male thread at 1-1/4 inch. The ES seal configuration provides a reliable face seal at the BSPP end, supporting leak-free connections in demanding hydraulic circuits.

Manufactured by Adaptall, this fitting is built from steel and offered in a straight configuration, making it well suited for applications where compact routing and direct port-to-tube alignment are required. It is a practical solution for connecting metric DIN tube lines to equipment with BSPP ported interfaces.

Question by: Shane M on Mar 13, 2026, 6:57 AM

got a DIN tube end that’s M52 x 2.0 (L42). is this the right adapter to go over to a 1-1/4 BSPP port?

Answer by: Customer Support on Mar 14, 2026, 5:24 PM

For that exact changeover, it matches up. Side 1 is a DIN tube connection with an M52 x 2.0 thread and L42 tube designation, and side 2 is a male BSPP with a G 1-1/4 - 11 thread (1-1/4 inch).

Will this here fitting hold up okay for hydraulics, or is it more for air lines and such?

This Adaptall fitting is definitely designed for hydraulic applications where you need to connect a metric DIN tube to a BSPP port. It’s made of steel for durability in those kinds of systems.

Question by: Dwayne G on Sep 21, 2025, 9:09 AM

What exactly is the thread setup on both ends of this fitting? Trying to match it up to what I got on my line and my port before I order.

Answer by: Customer Support on Sep 22, 2025, 10:52 AM

One end is a DIN tube connection sized at L42 with an M52 x 2.0 thread. The other end is a male BSPP thread, specifically G 1-1/4 - 11 at 1-1/4 inch. The BSPP side uses an ES face seal configuration, which keeps that end locked down against leaks. Both sides are male, so make sure your mating components are female on each end before you commit to ordering.
