SURIEEN R134a AC Recharge Hose Kit — 40" Low-Side Hose with Gauge, Brass Adapters, 600 PSI

The SURIEEN R134A AC Refrigerant Recharge Hose Kit is a 40-inch low-side charging hose with built-in pressure gauge and two 1/2" flare adapters for quick, accurate R134a recharge jobs.

If you service vehicle air conditioning systems or need an easy way to top up R134a refrigerant, this kit bundles a flexible recharge hose, a clear pressure gauge, and both left- and right-thread adapters so you can attach most canisters and service ports without guessing fittings. The components are made from reinforced rubber, fiber braid and brass fittings to withstand high working pressures and repeated use, and the gauge is calibrated for R134a to help you monitor charging precisely.

How does this kit connect to my car and refrigerant can?

Connection is straightforward: one end of the 40" hose features a 1/2" quick low-side coupler that fits the vehicle service port, while the other end accepts a 1/2" female flare fitting. The kit includes two 1/2" female-to-male flare adapters to match either left- or right-hand thread refrigerant cans. The coupler and adapters are solid brass for secure, leak-resistant mating.

• 40" hose length for flexible reach around engine bays
• 1/2" low-side quick coupler for standard AC service ports
• Two 1/2" female-to-male flare adapters (left- and right-thread)
• Brass fittings to reduce leaks and resist corrosion

Is the gauge accurate and safe to use?

The kit includes a pressure gauge marked for R134a so you can watch system pressure while charging. The gauge and hose are rated for a maximum working pressure of 600 PSI and a burst pressure up to 3000 PSI, giving a wide safety margin for common automotive AC service. The gauge face design makes readings easy to scan while charging.

• Gauge calibrated for R134a refrigerant readings
• Max working pressure: 600 PSI; burst: approximately 3000 PSI
• Clear, legible dial to help ensure proper charge levels

What materials and build quality can I expect?

The hose blends premium rubber with fiber braid reinforcement for flexibility and durability under heat and pressure. Brass couplers and adapter switch components increase longevity compared with plated or zinc fittings. The trigger-style dispenser is reusable, and the alloy and fiber construction helps resist kinking and abrasion during routine use.

• Reinforced rubber hose with fiber weaving for durability
• Solid brass coupler and adapter switch for heat resistance
• Reusable trigger-style dispenser for repeated jobs
