AC Charge Hose with Gauge, R134A Car AC Refrigerant Recharge Hose Kit, Come with R134A Piercing Can Tap 1/2”ACME Valve & R134A Quick Coupler Fits for Car Air Conditioning Refrigerant 250 PSI

Description

Product Overview

The SURIEEN AC Charge Hose with Gauge is a purpose‑engineered kit designed for automotive air‑conditioning maintenance. At its core is a 13 mm diameter hose constructed from a durable brass core encased in high‑grade rubber, delivering a balance of rigidity and flexibility that resists kinking while tolerating the pressures of refrigerant flow up to 250 psi. The hose terminates in a 0.5‑inch UNF thread on one end, compatible with standard 1/2″ ACME valve fittings, and a 1/4″ SAE male thread on the opposite side, allowing seamless integration with most vehicle service ports.

Integrated into the assembly is a compact, analog pressure gauge calibrated from 0 to 250 psi, providing real‑time feedback during charge operations. The gauge is mounted on a sturdy aluminum‑brass housing that protects the dial from impact and vibration. Adjacent to the gauge, a built‑in safety valve automatically vents excess pressure, safeguarding both the technician and the vehicle’s compressor.

Complementing the hose and gauge is a precision‑machined R134A piercing can tap with a 1/2″ thread. This tap pierces the high‑side service port without the need for additional tools, delivering a quick, leak‑free connection. On the opposite side, a low‑side adjustable quick coupler features a T‑type knob with an internal pin that locks securely when pressure is applied, then releases effortlessly when the knob is turned. This design eliminates the risk of accidental venting and ensures a tight seal throughout the charging process.

The kit is packaged in a compact 6.69 × 6.02 × 1.34 inch box, weighing just 3.52 ounces, making it ideal for both workshop shelves and mobile service vans. The bright blue color coding of the hose and gauge enhances visibility in cluttered environments, reducing the chance of mis‑identification during busy service intervals.

Usage

This kit is engineered for a wide range of usage scenarios, from routine maintenance on passenger cars to more demanding applications on light trucks and SUVs. When a vehicle’s AC system loses refrigerant due to a leak or simply requires a top‑up, the technician can connect the 1/2″ piercing tap directly to the high‑side service port, then attach the low‑side quick coupler to the corresponding low‑side port. The built‑in gauge displays the system pressure, allowing the operator to monitor the charge level and stop the flow precisely when the target pressure is reached.

Because the hose is constructed from brass and rubber, it tolerates temperature fluctuations from cold winter mornings to hot summer afternoons without degrading. The flexible rubber sheath also enables the hose to be routed around engine components, under the dashboard, or through tight engine bays without excessive bending. This flexibility is especially valuable for DIY enthusiasts who may be working in cramped garage spaces or on‑site at remote locations.

The kit is also suitable for home‑based air‑conditioning units that use R134A, R12, or R22 refrigerants. By swapping the appropriate can tap, the same hose and gauge can service residential split‑systems, providing a cost‑effective solution for seasonal recharging tasks. The safety valve and quick‑release coupler together ensure that even non‑professional users can operate the kit with confidence, minimizing the risk of over‑pressurization or accidental discharge.

Why Choose Us

Choosing the SURIEEN AC Charge Hose Kit means selecting a product that combines engineering precision with practical convenience. Each component is manufactured to exacting tolerances, ensuring a leak‑free connection that meets or exceeds OEM specifications. The brass core of the hose provides superior corrosion resistance compared to all‑plastic alternatives, extending the service life of the kit even when exposed to moisture or automotive chemicals.

Our commitment to quality is reflected in the rigorous testing each kit undergoes before leaving the factory. Pressure tests verify that the hose can sustain 250 psi without deformation, while the gauge is calibrated against certified standards to guarantee accurate readings. The quick coupler’s locking mechanism is tested for repeatability, ensuring that it will engage and release reliably after hundreds of cycles.

Beyond the hardware, SURIEEN offers dedicated customer support that includes technical assistance, troubleshooting guides, and a responsive warranty service. Should any component fail within the warranty period, we provide a replacement part or a full kit exchange, minimizing downtime for professional shops and hobbyists alike. This after‑sales commitment underscores our confidence in the durability and performance of the product.

Finally, the kit’s design emphasizes safety. The built‑in pressure relief valve prevents dangerous over‑pressurization, while the low‑side quick coupler’s auto‑shut‑off feature stops refrigerant flow the moment the gauge reaches the preset limit. These safety features reduce the likelihood of accidental exposure to high‑pressure refrigerant, protecting both the user and the vehicle’s compressor.

FAQ

What refrigerants are compatible with this kit?

The kit is primarily designed for R134A, which is the standard refrigerant in most modern automotive AC systems. However, the can tap can also be used with R12 or R22 if the appropriate adapter is installed, making the kit versatile for both vehicle and residential applications.

How do I know when the refrigerant charge is complete?

Watch the built‑in gauge as you add refrigerant. The gauge is calibrated to display pressure in psi. When the reading reaches the manufacturer‑specified target pressure for your vehicle (typically found in the service manual), the low‑side quick coupler will automatically shut off, preventing over‑charging.

Can I use this kit on a motorcycle or small engine?

Yes, the hose’s 13 mm diameter and flexible construction make it suitable for smaller engines, provided the service ports match the 1/2″ and 1/4″ thread sizes. Always verify the pressure specifications of the smaller system before charging.

What safety measures are built into the kit?

The kit includes a pressure relief valve that vents excess pressure, a low‑side quick coupler that auto‑shuts off at the set pressure, and a sturdy gauge housing that protects the dial from impact. These features work together to keep the user safe and the system protected.

How do I maintain the hose and gauge for long‑term use?

After each use, purge any remaining refrigerant from the hose, wipe the exterior with a clean cloth, and store the kit in a cool, dry place. Periodically inspect the gauge for accuracy using a calibrated reference gauge, and replace the hose if you notice any cracks or wear in the rubber sheath.
