Components for Refrigeration

The Refrigeration Components category includes the critical parts that manage refrigerant flow, pressure, temperature and phase change inside HVAC and refrigeration systems. These components ensure reliable cooling, prevent compressor damage and maintain efficiency across residential A/C, heat pumps, VRF/VRV, and light-commercial refrigeration equipment.

Here you’ll find expansion valves (TXVs/EXVs), filter driers, sight glasses, solenoid valves, service valves, pressure switches, refrigerant distributors, accumulators, receivers and defrost components. These parts support mini-splits, central A/C systems, rooftop units, heat pump systems, walk-ins, reach-ins and refrigeration circuits.

  • Expansion valves (TXV/EXV) for precise refrigerant metering and superheat control.
  • Liquid & suction filter driers to protect against moisture, acid and debris.
  • Sight glasses & moisture indicators for charge verification and diagnostics.
  • Solenoid & pressure-control valves for refrigerant flow and system protection.
  • Accumulators, receivers & distributors for safe refrigerant storage and routing.

When selecting refrigeration components, verify refrigerant type (R410A, R32, R454B, R22, CO₂), tonnage, pressure rating, connection size, flow requirements, operating temperature range and OEM compatibility. Proper component selection preserves compressor health, maintains capacity and ensures stable system operation.

Pro tip: Always replace the filter drier when opening the refrigerant circuit. A fresh drier protects the system from moisture and acid formation after service.
