YAMATIC Pressure Washer Whip Hose 4 ft — 3/8" Swivel Connector, 4000 PSI Steel-Braided Jumper

The YAMATIC 4 ft Pressure Washer Whip Hose is a steel-braided, 3/8" swivel-connected jumper designed to link pumps, reels and surface cleaners at up to 4000 PSI.

This heavy-duty 4-foot whip hose from YAMATIC is built for gas-powered pressure washers and hose reels. It combines a steel wire braided core with a wear-resistant rubber jacket and USA-standard steel 3/8" male NPT fittings for improved rust resistance. The hose accepts hot and cold water between 35°F and 212°F (0°C–100°C) and ships with a 3/8" quick-connect plug to simplify hookup to 3/8" pump outlets.

How does this whip hose make hookup and reel use easier?

The hose uses a swivel-style connector on one end and a fixed connector on the other, allowing the hose to align without twisting and reducing kinks when it’s wound on a reel. A 3/8" quick-connect plug is included to let you couple the hose to common pump outlets fast, saving time during setup or changeover.

• 3/8" swivel connector rotates to prevent hose torque.
• Fixed opposite end provides a secure pump or reel attachment.
• Included 3/8" quick-connect plug for rapid connections.

What pressure and temperature limits should I expect?

This jumper hose is rated for heavy commercial use with a working pressure up to 4000 PSI and a maximum rating cited at 4500 PSI. It tolerates water temperatures from 35°F to 212°F (0°C–100°C), making it suitable for cold-water rinses and most hot-water cleaning tasks within those limits.

• Working pressure: rated to 4000 PSI (4500 PSI max rating).
• Temperature range: 35°F–212°F (0°C–100°C).
• Designed for gas-powered high-pressure cleaners and related equipment.

Which applications is the 4 ft length best suited for?

The 4-foot whip hose is sized to serve as a short jumper between a pump and a hose reel or surface cleaner, and it fits in tight pump rooms and self-service carwash bays where longer hoses would tangle. YAMATIC also offers other lengths for different setups, but 4 ft is a common repair or replacement length for many reels and coil connections.

• Connector between pump and hose reel or heater coil outlets.
• Bypass/unloader or surface cleaner replacement hose (4 ft & 5 ft options).
• Short jumper hose for carwash bays and pump rooms.

What materials and fittings are used, and why do they matter?

The hose uses a steel wire braid under a durable rubber jacket to resist abrasion and maintain burst strength during frequent use. YAMATIC fits the hose with USA-standard steel 3/8" male NPT fittings that are more corrosion-resistant than plated aluminum, and the swivel end reduces stress on fittings during operation.

• Steel wire braid for strength and flex endurance.
• Wear-resistant rubber jacket helps prevent scuffs and leaks.
• Steel 3/8" male NPT fittings for improved rust resistance.

Who is this for: Technicians, carwash operators, pressure-washer rental companies and serious homeowners who need a rugged short jumper between pumps, surface cleaners or hose reels. If you require a compact, high-pressure connection that tolerates hot water and frequent winding on a reel, the YAMATIC 4 ft whip hose is a practical replacement or upgrade that balances durability with easy hookup. For other lengths and accessory options, YAMATIC’s Power Center Store carries additional jumper hoses and connectors, and customer support is available around the clock for technical or fit questions.
