S12MBT-S12MBT STRAIGHT

Description & Features

Designed for DIN metric tube compression connections, the S12MBT-S12MBT Straight is a steel union fitting that joins two 12mm OD heavy-series tubes in a straight inline configuration. Both ends conform to DIN 2353 and ISO 8434-1 standards, with M20x1.5 threads on each side and 24mm hex flats to accommodate standard tooling.

Built from straight steel and rated to a maximum dynamic pressure of 630 bar, this fitting is well-suited for high-pressure hydraulic circuits where a reliable, leak-free tube-to-tube connection is required. The overall length is 52mm, with a centerline length of 19mm and a 34mm body length, compact dimensions that support installation in space-constrained assemblies. The D2403-Equal series designation confirms this is a same-size, equal-end fitting on both ports.

Can this fitting handle getting bumped around much?

Answer by: Customer Support on Apr 4, 2026, 6:28 AM

This fitting is rated to a maximum dynamic pressure of 630 bar, so it's built to handle high-pressure hydraulic circuits. It should hold up fine under normal operating conditions, but excessive physical stress should always be avoided.
