Pressure Transducer for High-Pressure Systems
The Johnson Controls P499RCP-105C pressure transducer measures from 0 to 500 psi in pressure washer and industrial applications. It delivers a 0.5 to 4.5V DC output through a 3-pin Packard connector and operates on a 5V DC supply. The stainless steel housing carries an IP67 rating for dust and water resistance.
Sustained Load Behaviour Across Temperature Extremes
Accuracy remains within +/-1 percent of full scale while the sensor runs continuously between -40 and 185 degrees Fahrenheit. The three-wire circuit maintains a stable voltage signal without drift during extended duty cycles. Stainless steel construction resists corrosion and mechanical fatigue under constant pressure cycling.
Practical Limits of the SAE 45° Flare Interface
The male 1/4 inch SAE 45 degree flare connection seals directly into compatible ports without additional adapters. Installers must verify that the mating port matches the SAE flare angle and thread specification to avoid leaks. The fixed 500 psi upper range cannot be extended, so systems exceeding this pressure require a different transducer.

Questions about this item
How much heat can the P499 transducer handle during continuous outdoor use?
The unit operates reliably from -40 °F up to 185 °F, so it withstands typical pressure-washer duty cycles without overheating.
What connector and voltage must my system provide for the 3-pin Packard plug?
A 5 V DC supply feeding the three-wire 0.5–4.5 V output is required; the mating Packard connector is not included.
Will the 1/4 in SAE 45° flare port thread into my existing stainless-steel manifold?
Yes, the male 1/4 in SAE 45° flare fits standard flare fittings on stainless manifolds used in pressure-washer circuits.
