3/8 in Ultraflex Hydraulic Hose Assembly 30 in - High Pressure

Our review of this 3/8 in Ultraflex hydraulic hose assembly finds it best suited for technicians and fabricators who need a ready-made, high-pressure hose that installs quickly. The bottom line: this 30 in hose with 3/8 in female JIC ends is built for durability and reliable sealing under heavy loads, and its 5,583 psi working pressure plus abrasion-resistant cover make it a practical replacement or field repair part. It is not a custom-length solution, but for anyone needing a rugged, off-the-shelf 3/8 in JIC assembly, it is an easy, dependable choice.

Key Features

• Ready crimped ends: Both ends are factory crimped to 3/8 in female JIC fittings so the assembly installs faster and reduces leak risk compared with field-swaged joints.
• High working pressure: Rated at 5,583 psi, the hose handles demanding hydraulic systems and offers a wider safety margin for many mobile and industrial applications.
• Durable construction: The inner core and 2-wire steel braid provide strength for pressure cycling while the MSHA-certified outer cover offers abrasion resistance in rough environments.
• Temperature range: Operates across a broad range from -40F to 212F (with short-term tolerance to 248F), which suits both cold-start and hot-operating conditions.
• Meets and exceeds standards: Built to exceed SAE R2, R16 and R17 expectations, giving confidence for use where recognized hose performance is required.
• Value for money: Customers report good fit and function at common system pressures, making this a cost-effective off-the-shelf assembly.

Who It's For

This assembly is aimed at maintenance professionals, hydraulic technicians, and equipment owners who need a reliable 3/8 in hose with female JIC ends and high working pressure without the wait for custom fabrication. Its ready-made nature is ideal for emergency repairs, on-site replacements, or service trucks carrying common spare lengths.

It is less suitable for systems that require custom-length routing, specialized fittings other than 3/8 in female JIC, or hoses rated for continuous use above the published maximum temperature. Users needing metric fittings or non-JIC connections should look for a purpose-made alternative.

Pros & Cons

Pros
