Tigbear AC Manifold Gauge Hose Kit — 3‑hose 5 ft (60") for R404A/R12/R502, 45° 1/4" SAE, 500 PSI

Tigbear's 5ft AC Manifold Gauge Hose Kit is a three‑hose refrigerant charging set designed for R404A, R12 and R502 systems with 1/4" SAE female flare fittings and a 45° service port angle for easier access.

This three‑piece kit supplies the colored low, high and charge lines technicians and DIYers need for pressure testing, vacuuming and topping off compatible HVAC and refrigeration systems. Built with rubber hoses and iron‑plated copper heads, the set replaces worn or missing lines on many manifold gauge setups. Maximum working pressure is 500 PSI and burst pressure is 2500 PSI — suitable for the specified refrigerants but not for systems exceeding the hose pressure rating.

Will these hoses work with my refrigeration type and gauge fittings?

Yes — the hoses are intended for R404A, R12 and R502 refrigerants and use standard 1/4" SAE female flare threads to connect to most manifold gauges and service ports. They are a direct substitute for typical master gauge charging lines when those refrigerants are in use.

• Compatibility: R404A, R12, R502 systems only
• Connector: 1/4" SAE female flare thread for common manifolds
• Color coding: red = high, blue = low, yellow = charge
• Pressure limits: working 500 PSI, burst 2500 PSI

How long are the hoses and why choose 45° angled ports?

Each hose measures five feet (60" / 152 cm), a length chosen to give room to move around condensers and compressors without kinking. The service‑side fittings are formed at a 45° angle to make it easier to reach tight valve stems and access ports that sit close to frames or piping bundles.

• Length: 60 inches / 152 cm per hose for flexible reach
• Angle: 45° service port ends for better accessibility
• Flexibility: rubber construction resists bending stress
• Usage: suitable for bench, garage, or field service

What materials and durability features does the kit include?

The hoses combine durable rubber tubing with iron‑plated copper heads for a balance of flexibility and robust connection points. The construction is targeted at regular HVAC or refrigeration service tasks — not for systems where pressure might exceed stated limits.

• Hose material: reinforced rubber for flexibility and wear resistance
• Fittings: iron‑plated copper heads for corrosion resistance and sealing
• Rated pressures: 500 PSI working, 2500 PSI burst
• Service life: suitable for frequent charging and vacuum operations

How do I use these hoses safely during charging or vacuuming?

Attach the red hose to the high side, blue to the low side, and yellow to the manifold charge port or vacuum pump. Always confirm the refrigerant type and system pressure ratings before beginning; this kit is not rated for pressures above its specified limits.

• Setup: connect color‑matched hoses to gauge ports and service valves
• Vacuuming: yellow hose to vacuum pump; pull to required microns
• Charging: use yellow line for refrigerant transfer, monitor gauges
• Safety: check system pressure ratings and wear protective gear

Who is this for: The Tigbear 5ft AC Manifold Gauge Hose Kit suits professional HVAC technicians, refrigeration service shops and capable DIY installers who work with R404A, R12 or R502 systems. It’s ideal when you need reliable, color‑coded replacement hoses with common SAE fittings, a practical length for on‑site work and angled service ends for easier valve access. Do not use it on systems with pressures exceeding the hoses' rated capacity.
