Midland Industries D2700-LN-L22-L22 Bulkhead Union

Product Description

The MIDLAND INDUSTRIES D2700-LN-L22-L22 is a steel bulkhead union fitting designed for hydraulic tube connections in high-pressure fluid systems. It joins two L22 metric bite-type connections through a panel or bulkhead wall, creating a secure, leak-resistant passage between hydraulic circuits. Both connection ports use M30 x 2 threads and conform to DIN 2353 and ISO 8434-1 dimension standards. The fitting carries an anticipated pressure rating of 16 MPa and is finished with a trivalent chromium zinc plating for corrosion resistance. Licensed hydraulic technicians and industrial maintenance professionals are the typical installers of this component.

This fitting is used in steel metric compression tubing systems, particularly in mobile hydraulic equipment, industrial machinery, and fluid power circuits requiring a through-panel tube connection. It belongs to the D2700-LN Series of DIN bulkhead unions and is suited for applications where two hydraulic lines must be routed through a structural panel or enclosure wall while maintaining a fully rated pressure connection. The L22 x L22 configuration means both sides accept the same tube size, making it appropriate for straight-through bulkhead installations without a size transition.

Key Features

• Both ports are L22 metric bite-type, conforming to DIN 2353 and ISO 8434-1 standards
• M30 x 2 thread size on both connection ends
• Anticipated pressure rating of 16 MPa
• Trivalent chromium zinc-plated steel construction for corrosion resistance
• Designed for through-panel installation in hydraulic tubing systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for steel metric compression hydraulic tubing systems built to DIN 2353 and ISO 8434-1 standards, using L22 metric bite-type tube connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with DIN metric compression fittings. Depressurize and lock out the hydraulic system fully before removing or installing any fitting. Use the appropriate metric wrenches sized for M30 fittings and ensure tube ends are cleanly cut and deburred before seating the bite-type ferrule. Follow DIN 2353 assembly procedures for initial tube make-up to achieve proper ferrule bite and seal integrity.
