Description
Overview:
This braided leak off pipe is a durable small‐bore fuel line for managing low‐pressure flows in vehicle and machinery fuel systems. It uses a flexible rubber tube protected by a tough cotton overbraid with a black braided finish, helping resist abrasion and wear in busy engine bays. With a 5 mm inner diameter and a 5 m continuous length, it is well suited to injector leak‐off duties and other light fuel transfer tasks on cars, vans, plant, agricultural equipment, generators, and garden machinery. The pipe is compatible with diesel, petrol, and oil, and meets DIN SPEC 73379 Type B 1983. Rated to 150 psi (10 bar) working pressure, it supports reliable, leak‐free connections when paired with suitable fittings and clamps. Manufacturer Part Number (MPN): 200 439.
Key Features:
- 5 mm inner diameter and 5 m length for versatile routing and minimal joints
- Cotton overbraided jacket for enhanced abrasion resistance and long service life
- Fuel‐resistant inner suitable for diesel, petrol, and oil applications
- Rated to 150 psi (10 bar) working pressure for dependable performance
- Complies with DIN SPEC 73379 Type B 1983 for quality and safety consistency
- Flexible construction eases installation in confined spaces and reduces kinking
- Can be cut to length with a sharp blade for clean, accurate ends
- Fits typical 5 mm tails, barbs, and unions; secure with appropriate clamps
- Smooth bore helps maintain stable flow in leak‐off and feeder circuits
- Discreet black braided finish for neat, OEM‐style repairs and maintenance
Typical Applications:
Used for injector leak‐off and spill circuits on diesel engines, light fuel feed or overflow lines on small engines, and general low‐pressure fuel duties in workshops. Common across automotive, construction plant, agricultural machinery, generators, pressure washers, cement mixers, compact tractors, lawn mowers, and similar equipment where a robust, flexible, small‐diameter fuel pipe is required.
