Manifold Gauge Set R134A Air Con with Colour Coded Hoses

A manifold gauge set for servicing vehicle air conditioning systems that use R134A refrigerant. Used for testing, evacuation and filling, it gives you the main components needed to check high and low side pressures and carry out routine A/C work more confidently.

Useful for vehicle maintenance, garage servicing and workshop use where air conditioning performance needs checking before repair or recharge work. The manifold gauge set compares pressure readings against vehicle A/C specifications, helping when diagnosing faults, checking system condition or preparing the system for evacuation and refill. It suits mechanics, mobile technicians and experienced DIY users working on compatible automotive air conditioning systems using R134A only.

Colour coding across the gauges, valves and hoses helps make setup clearer when connecting the low, high and service lines. The large 70mm gauges are easier to read during testing, and the impact-resistant lenses add some protection in regular workshop handling. A sight glass allows you to view the refrigerant condition during service work, while the quick-connect fittings help speed up connection and removal. The supplied hose lengths give workable reach around the front of the vehicle, and the high pressure safety valve is a useful addition when carrying out repeated A/C servicing jobs.
