YNF16996 A/C pressure switch (114-5333) protects CAT305.5E2 air-conditioning systems with accurate pressure monitoring.
Direct replacement for 114-5333 A/C system pressure switch
Designed for CAT305.5E2 mini excavator
Provides accurate refrigerant pressure protection
Prevents compressor overload and system damage
Built with corrosion-resistant materials for long service life
The YNF16996 pressure switch, replacing OEM part 114-5333, is designed for the A/C system of the Caterpillar CAT305.5E2 excavator. This switch monitors refrigerant pressure levels and protects the air-conditioning system by signaling the compressor to stop when pressure is too high or too low, preventing damage, leaks, or overheating.
Constructed using high-quality corrosion-resistant brass and reinforced internal components, the switch ensures stable performance under continuous vibration and varying temperatures typical of excavator working environments. Its precise calibration ensures accurate pressure detection, improving A/C efficiency and extending compressor lifespan.
YNF16996 is widely used by repair shops, machinery owners, and global parts distributors due to its OEM-level compatibility, easy installation, and reliable performance. Replacing a faulty pressure switch restores normal HVAC operation, reduces downtime, and keeps the operator cabin comfortable.
