Midland Industries D0318-S30 Din Tube Nut S30 Steel

Product Description

The MIDLAND INDUSTRIES D0318-S30 is a DIN-standard tube nut designed for use in steel metric compression fitting assemblies. It features an S30 MBT (Metric Bite-Type) connection configuration and is manufactured from steel with a trivalent chromium zinc-plated finish for corrosion resistance. The M42 x 2 thread pitch and 29 mm body length conform to DIN 2353 and ISO 8434-1 dimension standards. With an anticipated pressure rating of 40 MPa, this fitting nut is suited for moderate- to high-pressure hydraulic line connections. Installation is performed by licensed pipefitters, hydraulic system technicians, or industrial maintenance professionals working on steel tube assemblies.

The D0318-S30 is used in hydraulic systems requiring DIN-compliant metric compression fittings. It is appropriate for industrial, mobile, and stationary hydraulic applications where S30-series MBT connections are specified. The trivalent chromium zinc-plate finish provides surface protection in environments where mild corrosion exposure is a concern. This tube nut is part of the D0318 Series and pairs with compatible DIN 2353 compression ferrule and body components to form a secure, leak-resistant tube joint.

Compatibility

Designed for use in DIN 2353 and ISO 8434-1 compliant hydraulic tube assemblies using S30 MBT connection components. Compatible with D0318 Series metric compression fitting bodies and ferrules of matching thread and tube size.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial pipefitter familiar with DIN metric compression fitting procedures. Depressurize and isolate the hydraulic circuit fully before disassembling or assembling any tube fittings. Use appropriate metric hand tools and follow DIN 2353 assembly procedures for bite-type fittings, including proper pre-assembly of the ferrule onto the tube before final tightening. Do not over-torque the tube nut, as this can damage the ferrule bite and compromise the seal.
