Engine Oil Pressure Switch with 1/8 BSP Thread for Farm Equipment SKU: QT42171

When oil pressure drops from pump wear, bearing damage, or low oil levels, this engine protection switch provides the early warning you need to prevent catastrophic engine failure. A failed or missing oil pressure switch leaves you blind to lubrication problems that can destroy an engine in minutes.

Why This Switch Matters

• 1/8 BSP threaded connection fits standard monitoring ports on most farm engines
• Sealed housing protects internal contacts from oil contamination and moisture
• Durable switching mechanism withstands engine vibration and temperature extremes
• Quick installation with basic tools saves downtime during critical seasons

Apply thread sealant to the 1/8 BSP fitting and tighten only until snug—over-tightening can crack aluminum engine blocks. With 55+ years of farm equipment experience, S&H Parts knows reliable engine protection starts with the right components.
