HVAC Tool Spare Parts & Service Kits
Genuine replacement parts and service kits for refrigeration and air conditioning tools and equipment. O-rings, seals, valve cores, hose fittings, couplers, repair kits, and complete service bundles — primarily from Mastercool, stocked in the UK for same-day dispatch. Essential for keeping professional HVAC tooling in service.
Manifold & Hose Parts
O-ring repair kits for 2-way, 4-way, and ball valve manifolds. Valve cores and valve core tools for service port maintenance. Hose fittings, adapters, and couplers for manifold hose replacement and repair. Mastercool manifold O-ring kits are available in Nitrile (standard), EPDM (for R744/CO2), and Viton (for high-temperature and aggressive refrigerant applications) — select the correct material for your refrigerant. Replacement manifold hoses and manifold parts are stocked separately.
Vacuum Pump Parts & Service
Vacuum pump oil, exhaust filters, and service components for Mastercool vacuum pumps. Change vacuum pump oil every 10–15 hours under heavy use. Milky or discoloured oil indicates moisture contamination and requires immediate replacement to maintain pump performance. Vacuum pump parts are stocked separately.
Condensate Pump Spares
Replacement parts for Aspen, Sauermann, and Blue Diamond condensate pumps including float switches, replacement tanks, sensor kits, and peristaltic pump tubes and heads. Keeping spare pump components on the van reduces call-back time on condensate pump failures. Condensate pump accessories are stocked separately.
Installation Kits & Combo Sets
Complete installation kits including the AC Pipe Insulation Kit (self-seal tube, tape, and adhesive), Mastercool R134a/R1234yf evacuation and charging combo kits, tube cutter sets, and flaring and swaging kits. Combo kits reduce procurement time and ensure all required components are available for the job. Browse all service kits for the complete range.
Leak Detector & Tool Parts
Replacement sensors, batteries, calibration vials, and keypad components for Mastercool electronic leak detectors. Keeping detector consumables stocked ensures tools remain calibrated and operational. Leak detector parts are stocked separately.
