Continental Contitech 20531743 Def Transfer Hose 250 Psi

Product Description

The CONTINENTAL CONTITECH 20531743 is a DEF transfer hose rated for diesel exhaust fluid (DEF) service in mobile and stationary fluid transfer applications. Built to handle a maximum working pressure of 250 psi, this hose is constructed to resist the corrosive properties of urea-based DEF solutions. It is sold in 1-foot increments with a 10-foot minimum cut length, making it a practical choice for custom-length installations. Licensed technicians and fleet service professionals who work with selective catalytic reduction (SCR) systems will find this hose suitable for routing DEF from storage tanks to dispensing equipment.

This hose is designed for use with diesel exhaust fluid in light-duty, medium-duty, and heavy-duty diesel SCR applications. Its black outer jacket provides resistance to UV exposure and physical abrasion in shop and field environments. Typical installations include DEF dispensing stations, bulk storage tank connections, and mobile service equipment where precise hose lengths are required. The per-foot pricing structure allows technicians to cut exactly what is needed from a 100-foot coil.

Installation Notes

DEF transfer hose installation is typically performed by diesel service technicians or fleet maintenance professionals. Depressurize and drain the DEF system before cutting or connecting hose segments to prevent fluid exposure. Use fittings and clamps rated for DEF service, as standard steel hardware can corrode when exposed to urea solutions. Follow equipment manufacturer guidelines and applicable SAE standards for hose routing, support spacing, and connection torque.
