Supco SLP1025 Low Pressure Switch – 10 PSI Cut-Out / 25 PSI Cut-In, SPST HVAC Refrigeration Control

The Supco SLP1025 Pressure Switch is a reliable, factory-calibrated low pressure control switch designed to protect and regulate HVAC and refrigeration systems. Featuring a 10 PSI cut-out (open on pressure drop) and 25 PSI cut-in, this SPST (single pole, single throw) switch delivers accurate and repeatable performance for heat pumps, air conditioning, and refrigeration equipment.

Built for durability and long service life, the SLP1025 uses a snap-acting, hermetically sealed stainless steel sensor for stable operation and excellent set-point accuracy. Its compact, lightweight design allows for direct mounting, while the encapsulated, non-adjustable construction ensures dependable operation without field calibration.

This pressure switch is compatible with HFC, HCFC, and CFC refrigerants, making it a versatile replacement option for many systems. The included ¼" SAE 45° female flare fitting with valve core depressor simplifies installation and servicing.
