Sejaede AC Manifold Gauge Set for Car A/C – 3-Way R134a/R12/R22/R502, 5ft Hoses & Adjustable Couplers, ±1.6% Accuracy

This compact manifold gauge kit is built to handle common auto refrigerants — R134a, R12, R22 and R502 — while giving hobbyists and technicians reliable pressure readings and leak-resistant connections. The set combines durable brass fittings, rubber-protected gauges with ±1.6% accuracy, and heavy-duty 5-foot color-coded hoses to speed up charging, evacuation and troubleshooting of car air conditioning systems.

How does this kit help me recharge or diagnose a car A/C system?

The three-way manifold provides separate high and low pressure ports plus a service port for charging, evacuation and pressure checks. Accurate gauges let you read operating pressures at a glance so you can size leaks, verify compressor performance, and apply correct refrigerant amounts.

• Separate high/low gauges with rubber guards for drop protection
• Yellow center hose for charging and vacuuming; red/blue for high/low sides
• Self-sealing and puncturing can taps for different refrigerant cans
• Brass fittings and precision threads reduce leakage during service

Is this manifold compatible with the refrigerant I use?

Yes — the Sejaede manifold supports multiple refrigerants commonly found in vehicles: R134a, older R12 systems, R22 and R502. The included adapters and seals make it flexible for various cans and service port types, but always follow refrigerant handling laws and safety procedures.

• Works with R134a, R12, R22 and R502 systems
• Includes R134a adjustable quick couplers and additional adapter seals
• Comes with spare rubber seal rings for R410A compatibility where needed
• Both self-sealing and puncturing can taps expand compatibility with different cylinder styles

What features make this kit durable and accurate for repeated use?

Durability comes from brass fittings, layered PVC hoses and sturdy gauge casings; accuracy is supported by calibrated high/low gauges rated to ±1.6%. The hoses resist kinks and burst pressures, while the rugged manifold body and accessories are intended for workshop conditions.

• High/low gauges with protective rubber boots and ±1.6% accuracy
• 5-foot, 4-layer reinforced PVC hoses — 600 PSI working pressure
• Heavy-duty brass connectors for corrosion resistance and long life
• Precision threading and tight seals to prevent refrigerant leaks

What accessories are included and how do they streamline service work?

The kit arrives ready-to-use: hoses, manifold, couplers, adapters and a storage case keep everything organized so you can move between vehicles without improvising. The valve core wrench and spare O-rings let you replace small parts on the spot and maintain reliable connections.

• 3-way manifold gauge and three 5ft color-coded hoses (blue, red, yellow)
• 2 adjustable R134a quick couplers, one adapter, and 3 spare rubber seal rings
• Valve core wrench for service port maintenance and tightening
• Compact storage case for transport and safe storage of components

Who is this for: The Sejaede AC Manifold Gauge Set is made for DIY mechanics, mobile technicians and garage pros who service automotive A/C systems and need a flexible, multi-refrigerant toolset. It’s suitable for routine charging, pressure checks, leak isolation and light diagnostic work — a practical choice if you value accuracy, durable fittings and ready compatibility with common refrigerants. Always use proper safety gear and follow local regulations when handling refrigerants.
