EVIL ENERGY 1/4 NPT Oil Pressure Sensor Tee Adapter – Stainless Steel 304, 1/4 NPT Female to Male with 1/8 NPT Female Port

Overview

The EVIL ENERGY oil pressure sensor tee adapter is designed to integrate gauges or sensors into oil lines with a compact, corrosion-resistant body. Constructed from 304 stainless steel, it stands up to demanding environments while keeping a clean, professional appearance.

What makes it practical

This adapter features precise thread sizing: outlet 1/4-18 NPT female, inlet 1/4-18 NPT male, and a center tap port of 1/8-27 NPT female. The 60-degree tapered NPT threads promote a tight seal when paired with appropriate sealing methods.

• Material: corrosion-resistant 304 stainless steel for durability in oil systems
• Sealing: tapered 60-degree NPT threads to minimize leaks; PTFE tape is recommended for best results
• Versatility: supports oil pressure and temperature gauge/sensor installations
• Installation: clean threads and apply PTFE tape for reliable connections

Real-world uses

Ideal for automotive, industrial, or custom-build projects where dedicated monitoring lines are valuable. The center-port connection can accommodate a secondary sensor or sample line, enabling flexible monitoring without rearranging main lines.

• Automotive engines and transmissions
• Machinery and equipment with oil cooling loops
• Custom builds requiring accessible sensor taps

Build quality and maintenance

Quality you can feel in the metal: the 304 stainless steel finish provides a smooth, uniform surface that resists corrosion and is easy to clean. The compact geometry keeps installation neat, reducing clutter around the engine bay.

Care and installation tips

Before final assembly, wrap the threads with PTFE tape and tighten to a snug fit. Periodically inspect the connections in demanding conditions and replace packing if you notice signs of wear.
