Tigbear R134A Recharge Hose Kit — 59" Low-Side Charge Hose with Self-Sealing Can Tap and Gauge

The Tigbear R134A Refrigerant Charge Hose Kit is a complete low-side recharging solution featuring a self-sealing can tap, a quick coupler, and a 59" high-pressure hose with an easy-to-read gauge.

This kit bundles the key tools needed to top up R134A automotive or appliance systems from the low-side service port without special training. Built with brass fittings, a safety valve and a durable rubber hose, the set is designed to reduce refrigerant loss and improve control when connecting sealed R134A cans. The included gauge and clear coupling make it straightforward to monitor pressure and engage or disengage connections safely.

How do I connect the Tigbear kit to my vehicle or appliance?

Attach the 13mm low-side quick coupler to the system's service port and thread the 1/2" RH self-sealing can tap onto compatible R134A cans. The coupler locks over the port with six sealing balls for a secure seal, while the can tap prevents refrigerant from escaping until engaged.

• Use the 13mm low-side quick coupler for standard R134A service ports.
• Thread the 1/2" RH can tap only onto self-sealing R134A cans (not puncture-style).
• Open the gauge valve to allow refrigerant flow once all connections are secure.

What safety and pressure limits should I know before using it?

The nylon- and rubber-reinforced hose is rated for 600 psi working pressure and tested to higher burst values, while the gauge reads up to 250 psi for system monitoring. A built-in safety valve and an auto-close quick coupler are included to help prevent accidental discharge during hookup and removal.

• Gauge maximum reading: 250 psi for clear low-side monitoring.
• Hose working pressure: rated 600 psi, burst-tested to 3000 psi for durability.
• Integrated safety valve and self-closing coupler reduce refrigerant loss.

Which refrigerant cans work with the included can tap?

The can tap is designed to fit R134A refill cans that use a 1/2" RH self-sealing ACME thread and converts to a 1/4" SAE male fitting for the hose. It is not compatible with cans that require puncture-style openers, so check the can threading before attempting to connect.

• Compatible with self-sealing R134A cans featuring 1/2" RH thread.
• Not suitable for puncture-type refrigerant can designs.
• Converts 1/2" female ACME to the hose’s 1/4" SAE male interface.

How easy is it to use this kit for a DIY recharge?

The kit is aimed at quick, low-side recharges: the long 59" hose gives flexibility around engine bays and refrigerators, while the large, color-readable gauge simplifies pressure checks. Brass fittings and clear mechanical connections make hookups straightforward; however, basic knowledge of A/C service ports and safe refrigerant handling is recommended.

• 59" hose provides reach to access cramped service ports.
• Large readable gauge helps you monitor pressure without guesswork.
• Self-sealing can tap and auto-close coupler cut down on leaking refrigerant.

Who is this for: The Tigbear R134A Charge Hose Kit is intended for DIY mechanics, fleet or small-shop technicians, and homeowners who need a reliable, portable way to recharge R134A systems through the low-side port. It’s ideal for users who prefer a self-sealing can tap and a long, durable hose with a clear pressure gauge, but it’s not a replacement for professional diagnostics or complex A/C repairs.
