Tigbear R1234YF Refrigerant Charge Hose Kit — 59" Hose, 250 PSI Gauge & 1/2" LH Can Tap

The Tigbear R1234YF Refrigerant Charge Hose Kit is a complete low‑side recharging solution that includes a 250 PSI gauge, 59" hose, 14mm quick coupler and a 1/2" LH puncture can tap for R1234yf cans.

This compact recharge kit gives you the tools to add R1234YF (and R134A where noted) refrigerant to automotive A/C or refrigeration systems from the low‑side service port. Built from brass fittings and reinforced rubber hose, the set was designed for routine top‑ups and troubleshooting pressure readings without needing bulky shop equipment. Safety and convenience features — such as an auto‑closing quick coupler and a built‑in shutoff valve — help reduce refrigerant loss while you work.

How does this kit measure system pressure and indicate charge level?

The kit includes a large, color‑coded gauge rated to 250 PSI which translates low‑side pressure into an easy visual reference. While gauges don't replace a full load or leak diagnosis, the dial gives quick confirmation of whether the system is pressurized and roughly where the pressure sits relative to normal ranges.

• 250 PSI maximum gauge rating with colored zones for fast reading.
• Gauge compatible with R1234YF and usable for many R134A checks.
• Clear face and large numbers for easy visibility when working in engine bays.

Can I attach this to modern R1234YF service ports safely?

The kit's 14mm low‑side quick coupler is built to fit R1234YF low‑side ports and locks with six sealing balls to minimize leaks. It features an auto‑close mechanism so the coupler seals when disconnected, reducing accidental venting of refrigerant during attachment and removal.

• 14mm quick coupler with 1/4" male thread for R1234YF low side ports.
• Six‑ball sealing design for a tight connection and reduced leakage.
• Automatic close function prevents unnecessary refrigerant release.

What type of refrigerant cans work with the included can tap?

The included can tap is sized for puncture‑style R1234YF cans with a 1/2" LH ACME female connection; it pierces and allows controlled flow from those cans into your charging hose. It is not compatible with self‑sealing cans or other thread sizes, so confirm the can design before trying to attach.

• 1/2" LH ACME female to 1/4" SAE male can tap for puncture‑type R1234YF cans.
• Designed to puncture non‑self‑sealing cans; do not use on self‑sealing types.
• Provides controlled release when charging to help avoid sudden overfill.

How durable and easy to use is the Tigbear recharge hose kit?

Constructed from brass fittings and heavy‑duty rubber hose, the Tigbear kit balances longevity with flexibility. The 59" hose length helps reach awkward service ports while keeping the gauge and can outside tight engine areas. Installation and operation are straightforward for anyone familiar with basic A/C top‑ups.

• 59" reinforced rubber hose rated 600 PSI working, 3000 PSI burst pressure.
• Brass fittings reduce corrosion and maintain reliable seals over time.
• Simple hookup—add refrigerant slowly and monitor the gauge for safe charging.

Who is this for? The Tigbear R1234YF Refrigerant Charge Hose Kit is ideal for DIYers, fleet technicians, and refrigeration hobbyists who need a portable, affordable way to check low‑side pressures and add refrigerant from puncture‑style R1234YF cans. It’s suited for routine top‑ups and quick troubleshooting, but not a substitute for professional diagnosis when systems need repair or for working with self‑sealing can valves.
