Overview

The Boltigen 3/8 ID Transmission Oil Cooler Hose is a durable, professional-grade line designed to connect oil coolers to transmissions and hydraulic systems. Built for demanding automotive, industrial, and off-road environments, it pairs high-temperature tolerance with reliable flexibility, helping you maintain steady performance under tough conditions.

This hose is suited for practical maintenance tasks where a secure, heat-resistant connection matters. It presents a balanced blend of strength and pliability, making it a thoughtful choice for both shop projects and field repairs without overpromising results.

Key specifications

  • Inner diameter: 3/8 inch (9.5 mm); outer diameter: 0.67 inch (16.5 mm); length: 10 feet
  • Working pressure: 300 PSI; burst pressure: 1800 PSI
  • Temperature range: -40°F to +302°F
  • Construction: durable inner polyester braid; tough CPE outer layer
  • Fluid compatibility: transmission fluid, oil, hydraulic fluids, lubricants, and gasoline
  • Standards: SAE J1532 compliant for professional-grade reliability

Durability and performance

The dual-layer design combines a reinforced inner braid with a rugged outer sheath. This structure helps resist abrasion and oil exposure while maintaining flexibility for routing in tight engine bays or compact machinery. The combination is geared toward longevity in environments that demand heat tolerance and steady flow.

  • Polyester braid supports high-pressure transmission paths
  • CPE outer layer provides weather and chemical resistance
  • Wide temperature tolerance supports operation across extreme climates

Applications and usage

Use this hose to link oil coolers with transmissions, or in other cooling and hydraulic circuits that require a reliable, high-temp, high-pressure hose. It is suitable for automotive repairs, industrial equipment, and off-road vehicles where a robust coolant or hydraulic connection is beneficial.

  • Automotive repairs and maintenance projects
  • Industrial equipment cooling and hydraulic lines
  • Off-road and heavy-duty vehicles needing resilient fluid transfer

Usage guidelines

For best results, verify fit before installation, keep runs free of sharp bends, and minimize kinks. Use appropriate clamps and routing to avoid excessive movement that could wear the inner braid or outer layer over time. Regular inspection can help identify wear early.
