AUTO METER Short-Sweep Oil Pressure Sender 2242 — 1/8" NPT with 1/4" Adapter, US-Made

The Auto Meter 2242 is a short-sweep electric oil pressure sender designed to work with Auto Meter short-sweep gauges, featuring a 1/8" NPT male thread and a 1/4" NPT adapter for flexible fitment.

This compact sender converts oil pressure into an electrical signal for compatible short-sweep gauges. Machined in the United States, it provides a direct, vehicle-specific fit for applications that require a short-sweep response. The package includes the sender and a 1/4" NPT adapter so you can match your engine’s port without sourcing extra fittings.

What does this sender do for my oil pressure gauge?

The 2242 translates hydraulic oil pressure into an electrical signal tailored for Auto Meter short-sweep electric gauges. That signal moves the gauge needle across a short arc, which is ideal for instrument panels designed for that sweep type. It ensures the gauge receives the correct range and responsiveness for accurate display.

• Converts pressure to electrical output compatible with short-sweep gauges
• Optimized for Auto Meter gauge calibration to preserve accuracy
• Short-sweep response reduces needle travel for compact gauge faces

How do I install the 2242 sender in my vehicle?

Installation is straightforward for anyone comfortable with basic engine plumbing and electrical connections. The sender threads into a 1/8" NPT port; if your engine uses a 1/4" port, the included adapter provides the correct transition. Make sure electrical connections are secure and the engine is cool before beginning.

• Thread type: 1/8" NPT male — adapter included for 1/4" NPT ports
• Use thread sealant or Teflon tape rated for oil systems to prevent leaks
• Connect wiring to the gauge per Auto Meter wiring instructions

What are the physical and compatibility details I should know?

The 2242 sender is compact and lightweight, packaged to minimize bulk. It’s a vehicle-specific fit for systems that use short-sweep electric oil pressure gauges. Built in the United States, the sender meets the build and tolerance expectations for performance-oriented dashboards.

• Thread: 1/8" NPT male; includes 1/4" NPT adapter fitting
• Package dimensions: 0.508 H x 19.812 L x 8.636 W cm; package weight: 0.4 lb
• Fit type: vehicle specific; country of origin: United States

How can I ensure reliable long-term performance?

Use proper installation techniques and compatible gauges to maintain accuracy and durability. Avoid overtightening the sender to prevent thread damage; select thread sealant suited for oil systems. Periodic inspection of the wiring and connection points helps catch issues before they affect gauge readings.

• Hand-start then torque to recommended specification to protect threads
• Use oil-compatible sealant and check for leaks after startup
• Inspect electrical connections periodically for corrosion or looseness

Who is this for: The Auto Meter 2242 is intended for drivers, mechanics, and hobbyists who use Auto Meter short-sweep electric oil pressure gauges and need a compact, vehicle-specific sender. It suits restorations, performance builds, or replacements where a short-sweep gauge will be installed and where a 1/8" or 1/4" NPT port must be accommodated. If you require straightforward compatibility with Auto Meter short-sweep instruments and a U.S.-manufactured sender, the 2242 is a practical choice.
