Midland Industries D2603-S14-S14-S10 Union Tee Steel

Product Description

The MIDLAND INDUSTRIES D2603-S14-S14-S10 is a steel union tee fitting designed for metric bite-type hydraulic tube connections. It joins two S14 ports and one S10 port in a tee configuration, allowing a branch connection in a high-pressure hydraulic line. The fitting carries a pressure rating of 63 MPa and conforms to DIN 2353 and ISO 8434-1 dimensional standards. A trivalent chromium zinc-plated finish provides corrosion resistance in demanding service environments. Hydraulic system technicians and fluid power specialists install this fitting when routing or branching steel tubing in mobile or industrial hydraulic circuits.

This union tee is suited for industrial and mobile hydraulic applications where metric bite-type fittings are specified. The two S14 ports use M22 x 1.5 threads, and the S10 branch port uses M18 x 1.5 threads. Typical installations include hydraulic power units, agricultural equipment, construction machinery, and industrial presses where DIN-standard fittings are required. The union tee style allows assembly and disassembly without rotating the tubing, which is practical in tight or congested plumbing layouts.

• Conforms to DIN 2353 and ISO 8434-1 dimensional standards
• Three metric bite-type ports: two S14 (M22 x 1.5) and one S10 (M18 x 1.5)
• Trivalent chromium zinc-plated steel construction for corrosion resistance
• Union tee design permits line disassembly without rotating tubing
• Part of the D2603 Series steel metric compression fitting family

Compatibility

Designed for use in hydraulic systems requiring DIN 2353 and ISO 8434-1 compliant metric bite-type fittings. Compatible with S14 metric tube connections on ports 1 and 2, and S10 metric tube connections on port 3.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with DIN metric compression fitting assembly procedures. Depressurize and isolate the hydraulic circuit completely before disassembling any lines or installing this fitting. Ensure tubing ends are cut square, deburred, and properly formed before seating the bite ring. Torque connections according to the applicable DIN 2353 assembly specifications for the tube size and fitting material.
