Oil Pressure T Fitting 1/8 npt

OVERVIEW

This isn''t just any brass fitting; it''s a faithful reproduction of the legendary EMPI GTV era hardware that defined the golden age of VW performance. For decades, air-cooled enthusiasts had to scour swap meets and forum classifieds for New Old Stock (NOS) pieces just to add a simple oil pressure or temperature gauge to their dash without butchering their engine case. Appletree Auto is proud to offer this authentic EMPI Oil Pressure T Fitting, which solves the age-old dilemma of limited real estate on the oil pressure relief passage. By utilizing this CAD-designed masterpiece, you can maintain your factory oil pressure warning light while simultaneously plumbing in up to three separate 1/8-27 NPT sending units. This makes it the ultimate solution for builders looking to monitor both oil pressure and temperature on a single high-performance dual-port or single-port engine without the need for messy "sandwich" adapters or drilling and tapping the block.

Crafted from high-quality cast brass for superior corrosion resistance and a period-correct look, this T-fitting is engineered to withstand the high-frequency vibrations and extreme thermal cycles of a hard-working flat-four. The inclusion of the stylish, recessed EMPI logo isn''t just for show; it signifies a commitment to the quality and heritage that made the brand a household name in the air-cooled world. Whether you are building a concours-quality Cal-Look Bug or a rugged off-road sand rail, this fitting ensures your VDO or Autometer gauges receive a steady, leak-free signal. Its compact geometry allows for easy installation in the tight confines of the engine bay, specifically near the distributor and fuel pump, ensuring that you don''t have to compromise on functionality or aesthetics. Protect your high-dollar engine investment by keeping a close eye on your engine''s vitals with a part that looks as good as it performs.

PRO TIPS

1. Proper Thread Sealing and Grounding

When installing your sending units into the T-fitting, it is vital to use a high-quality thread sealant, but you must be careful with the application. Many oil pressure and temperature sending units rely on the brass body of the fitting to complete the electrical ground circuit to the engine case. If you wrap the threads too heavily with Teflon tape, you may insulate the sensor, causing your gauges to give erratic readings or fail to work entirely. We recommend using a small amount of liquid thread sealer or a single wrap of tape, leaving the first two threads bare to ensure a solid metal-to-metal contact for grounding purposes.

2. Clocking and Clearance Checks

Before you tighten the T-fitting into the block, do a "dry fit" to check the clearance with your distributor and fuel pump. Depending on which distributor you are running (especially larger HEI units or 009 units with vacuum canisters), space can be very tight. You want to "clock" the fitting so that the sending units are positioned where they won''t vibrate against other components. If the fitting doesn''t line up perfectly when hand-tight, don''t over-torque it to reach the next rotation; instead, use a thin copper crush washer to adjust the final resting angle, ensuring a leak-free seal without stressing the brass threads in the magnesium or aluminum engine case.

3. Managing Heavy Sending Units

If you are planning to run multiple large sending units, such as a bulky VDO oil pressure sender and a temperature sender simultaneously, be mindful of the weight and leverage being placed on the single male 1/8 NPT neck of the fitting. High-RPM engine vibrations can cause fatigue over time if the assembly is excessively heavy. In extreme high-performance or off-road racing applications, it is a "pro move" to use a short braided stainless steel hose to remote-mount the T-fitting to the firewall or a bracket. This removes the weight from the engine case and protects your sensors from direct engine heat and vibration, significantly extending the life of your electronic sending units.
