Reddot Pressure Switch Hi 250-190 PSI RD549120P

The Reddot pressure switch listed here is a switch type component supplied as part number RD549120P. It is described as a high pressure switch with an operating range of 250-190 PSI, and it is sold as each. For buyers matching an existing cooling system component, the part number and pressure range are the most important checkpoints before ordering.

This item sits in the cooling product group and is identified under AC components. That makes the pressure specification especially important, because a switch with the wrong opening and closing range will not suit the intended system application. If you are replacing an existing switch, confirm the current part number, the pressure rating, and the system arrangement before selecting this part.

Reddot identifies the product as a pressure switch with a 12 month warranty. The listed details are limited to the part number RD549120P, the pressure range of 250-190 PSI, and its classification as a switch. Where a cooling circuit depends on a specific pressure signal, those details are the practical points to compare against the removed unit or service information.

Because no fitment list is supplied for this item, it should be treated as a part-number-matched component rather than a universal replacement. That approach helps avoid ordering errors when dealing with cooling or air conditioning controls, where switch calibration matters as much as physical connection style.

Application and Buying Notes

Before ordering, compare the existing switch details against RD549120P and check that the required pressure range is 250-190 PSI. That pressure rating is the key functional detail supplied for this item, and it needs to align with the system it is intended to control. If the current component shows a different range, do not assume this switch will be suitable.

The item is identified as a cooling and AC components part, so it should be matched with care to the relevant system specification rather than by appearance alone. Pressure switches can look similar while operating at different thresholds, and a mismatch can affect how the system responds. The safest reference points are the part number, the stated pressure range, and the original application details.

This product is supplied by the each, which is useful if you are replacing a single failed switch rather than ordering a kit or assembly. The 12 month warranty provides a defined period of cover, but it does not replace the need to verify compatibility before purchase. Where possible, check the old part label, service records, or the vehicle system specification and make sure they correspond with RD549120P.

If you are unsure whether the existing component is the same as this Reddot switch, pause and confirm the part number and pressure specification first. For cooling system control parts, that step is more reliable than judging from generic switch style or connector position alone. Matching the listing details carefully is the best way to reduce the risk of getting the wrong replacement.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number RD549120P helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Relevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty 12 Months, Product Group 2 AC COMPONENTS, Part No. RD549120P, Brand REDDOT, Description SWITCH - PRESSURE HI 250-190 PSI, Product Group 1 COOLING.

SWITCH - PRESSURE HI 250-190 PSI. Part number RD549120P should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number RD549120P, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm fitment by matching the existing part number RD549120P and the stated 250-190 PSI pressure range against the vehicle or system application before ordering.
