3/8 in Ultraflex Hose Assembly with 3/8 in Female JIC Ends - Durable

In this review of the 3/8 in Ultraflex hose assembly the bottom line is clear: this hose is built for technicians and operators who need a heavy-duty, abrasion-resistant hydraulic connection that installs easily and holds reliable pressure. The review focuses on fit, durability and working pressure; the assembly arrives crimped on both ends with 3/8 in female JIC fittings and a rated working pressure of 5,583 psi, which makes it a practical choice for mobile and industrial hydraulic repairs where a strong, ready-to-use hose is needed.

Key Features

• Pre-crimped ends: Comes with 3/8 in female JIC fittings on both ends for quick, leak-minimizing installation into existing hydraulic systems.
• High working pressure: Rated to 5,583 psi, providing reassurance for demanding hydraulic circuits and heavy-duty applications.
• Two wire steel braid core: The 2 wire steel braid inner core delivers consistent strength and resists burst and fatigue over repeated cycles.
• MSHA-certified outer cover: A tenfold abrasion-resistant synthetic rubber cover resists ozone and weather, extending service life in harsh environments.
• Wide temperature range: Usable from -40F to 212F (with short-term exposure up to 248F), covering most field and shop operating conditions.

Who It's For

This hose assembly suits mechanics, field service technicians, and shop professionals who need a ready-to-install replacement hose that meets or exceeds SAE R2/R16/R17 expectations and withstands abrasive conditions. It is ideal for systems that use 3/8 in female JIC fittings and require a robust 84 in length for reach without adapters.

Those who should look elsewhere include users needing specialized fittings, metric-threaded ends, or a hose with a different internal diameter or working pressure. If you require a flexible low-pressure line or PTFE chemical resistance, pick a hose designed specifically for those conditions.

Pros & Cons

Pros

• Strong working pressure of 5,583 psi supports demanding hydraulic systems.
• Durable 2 wire steel braid core with an MSHA-certified, abrasion-resistant cover improves longevity in rough use.
• Pre-crimped 3/8 in female JIC ends simplify installation and reduce leak points.

Cons

• Length and fittings are fixed at 84 in and 3/8 in female JIC, which limits flexibility for systems needing different end types or shorter hoses.
