T-Adapter, for 2 Sending Units 1/8 NPT Femal 1/8 NPT Male

OVERVIEW

Monitoring your engine''s oil health is the single most important factor in ensuring the longevity of your air-cooled Volkswagen. The EMPI T-Adapter is the professional solution for enthusiasts who refuse to compromise between safety and performance data. This high-quality brass fitting allows you to split a single 1/8-inch NPT oil port into two separate 1/8-inch NPT female ports. This is a critical upgrade for anyone looking to maintain their factory "idiot light" for immediate low-pressure warnings while simultaneously running a precision VDO or aftermarket oil pressure gauge. By installing this adapter, you eliminate the need for drilling or tapping your engine case, providing a clean, bolt-on solution for expanded instrumentation on your Type 1, Type 2, or Type 3 engine.

Crafted from solid, corrosion-resistant brass, this T-adapter is designed to withstand the high vibrations and heat cycles common in VW engine compartments. Whether you are building a high-performance street machine, a rugged off-road rail, or a concours-level restoration, having accurate real-time data is paramount. This adapter is particularly useful when installing oil temperature senders or secondary pressure switches in tight spaces. Because it uses the industry-standard 1/8-inch NPT threading, it is compatible with the vast majority of aftermarket sending units found in the VW community. Don''t leave your engine''s survival to chance; expand your monitoring capabilities with this essential EMPI component and keep a watchful eye on your oiling system at all times.

FITMENT

This adapter is designed for use with 1/8-inch NPT ports and sending units. Please note that many stock VW engine cases use a 10mm x 1.0 thread; an adapter may be required to convert the case port to 1/8-inch NPT before installing this T-fitting. It is commonly used on the following models:

• Volkswagen Type 1: Beetle, Bug, and Super Beetle (All Years)
• Volkswagen Type 2: Bus, Transporter, Kombi, and Westfalia (1950-1979)
• Volkswagen Type 3: Fastback, Squareback, and Notchback (All Years)
• Volkswagen Type 4: 411 and 412 Models
• Volkswagen Karmann Ghia: Coupe and Convertible (All Years)
• Volkswagen Thing: Type 181 (1973-1974)
• Custom Builds: Dune Buggies, Sand Rails, Baja Bugs, and Trikes using air-cooled VW powerplants.

PRO TIPS

Tip 1: Ensure Proper Grounding for Sending Units

Most oil pressure sending units, especially VDO styles, require a solid ground through the body of the sender to the engine case to function correctly. When using this brass T-adapter, avoid over-using Teflon tape on the threads. Excessive tape can insulate the connection and prevent the sender from grounding, leading to dead or erratic gauge readings. If you must use sealant, apply a small amount of liquid thread sealer to the middle of the threads, leaving the first few threads bare to ensure metal-to-metal contact between the adapter and the engine block.

Tip 2: Check for Clearance and Vibration Support

Adding a T-adapter and two sending units increases the "lever arm" length off the engine case. In high-vibration environments, such as off-road racing or high-RPM street builds, the weight of two heavy senders can put stress on the adapter. Always mock up the installation to ensure the senders do not interfere with your distributor, spark plug wires, or engine tinware. If the assembly feels heavy, consider using a remote relocation hose to move the T-adapter and senders off the engine block and onto the firewall or inner fender to prevent fatigue cracks in the brass.

Tip 3: Be Mindful of NPT vs. Metric Threading

It is a common mistake in the VW world to confuse 1/8-inch NPT with 10mm x 1.0 metric threads. While they look similar, they are not interchangeable and forcing them will ruin the threads on your engine case. Most stock VW oil pressure switch holes are 10mm. To use this 1/8-inch NPT adapter on a stock case, you must first install a 10mm male to 1/8-inch NPT female adapter. Always verify your thread pitch before installation to avoid costly damage to your magnesium or aluminum engine case.
