YAMATIC 5/16" Pressure Washer Hose 50 ft — Steel-Braided, 3/8" Swivel Quick-Connect, 4000 PSI

The YAMATIC 5/16" Pressure Washer Hose is a 50-foot, steel-braided, non-marking hose with 3/8" swivel quick-connect fittings built for 4000 PSI working pressure and reliable hot-or-cold cleaning performance.

Built for professionals and dedicated DIYers who need a durable, flexible hose that resists kinks and handles both high pressure and high temperature, this YAMATIC hose combines a steel wire braid core with a wear-resistant rubber jacket. It connects quickly to standard 3/8" quick-connect systems and is sized to balance flow and maneuverability on reels, guns, and surface cleaners.

How does the swivel quick-connect system reduce hose twist?

The hose uses 3/8" swivel quick-connect fittings with a steel plug and brass socket on each end so the connection can rotate independently of the hose body. That decreases torque transfer when you pivot the wand or move around corners, reducing kinks and wear at connection points.

• 360° swivel fittings to minimize twist during operation
• Steel plug and brass socket for long-lasting mechanical strength
• Quick-connect design for fast attachment and removal on compatible machines

What pressure and temperature can this hose safely handle?

YAMATIC engineered the hose for a 4000 PSI working pressure and a 12000 PSI burst rating, suitable for commercial-grade washers and demanding residential jobs. The rubber jacket and internal construction are rated from 15°F up to 212°F, so it tolerates cold starts and hot-water cleaning tasks without losing flexibility.

• 4000 PSI working pressure for heavy-duty cleaning
• 12000 PSI burst rating for safety margin under surges
• Operating temperature range of 15°F to 212°F for seasonal versatility

Will this hose fit my pressure washer and accessories?

This 5/16" inner-diameter hose uses 3/8" quick-connect fittings, making it compatible with many popular brands that use 3/8" systems. It works well with reels, pro guns, and surface cleaners used in commercial and residential setups, though M22 or 14mm systems need the correct adapter available from YAMATIC.

• Designed for 3/8" quick-connect systems (Simpson, Generac, Honda, DeWalt, and more)
• Use YAMATIC adapters for M22/14mm conversions when required
• Not intended for garden-hose (spigot) connections

How does the hose construction affect durability and handling?

The hose combines a tensile steel wire braid core with a wear-resistant rubber outer jacket to withstand abrasion, repeated flexing, and high-pressure cycling. Its 5/16" ID delivers a balance of flow and responsiveness—more support than smaller bore hoses without the bulk of larger-diameter lines—making it easier to reel and maneuver on job sites.

• Steel wire braided core for tensile strength and burst resistance
• Wear-resistant rubber jacket protects against cuts and scuffs
• 5/16" inner diameter for balanced flow and easier handling

Who is this for? Install the YAMATIC 5/16" x 50ft pressure washer hose if you need a professional-grade replacement or upgrade for commercial cleaners, pressure-washing contractors, or serious homeowners. It’s suited to users who require a mid-bore hose that resists kinks, accepts 3/8" quick-connect fittings, and performs in both hot- and cold-water cleaning applications.
