MODEL 50040: MALE HEX AIR TANK PLUG – 1/4" MALE NPT
PRECISION CAPPING FOR AUXILIARY AIR PORTS
Seal off open, unused manifold ports and protect the constant line pressure of your custom pneumatic configuration with the premium Kleinn Model 50040 Male Hex Air Tank Plug. When engineering a custom onboard air system, managing empty ports effectively is critical for maximizing overall efficiency. This high-performance mechanical fitting delivers a reliable, leak-proof barrier that stops the slow system pressure drops often caused by lower-quality components, preventing your compressor from cycling on unnecessarily.
INDUSTRIAL-GRADE BRASS RELIABILITY
The Model 50040 is machined entirely from premium solid brass, ensuring a component that easily handles high-vibration off-road environments and resists the corrosive effects of under-chassis moisture and road grime. Cut to precise tolerances, the standard 1/4" Male NPT threads establish a perfect mechanical fit with any universal pneumatic component. The integrated low-profile hex head allows for optimal flat wrench engagement, providing a permanent port solution that remains simple to loosen if your system layout changes down the road.
Why Choose the Model 50040 Hex Plug?
- Universal 1/4" Male NPT Thread: Seamlessly matches the most common sizing configurations found on auxiliary tank bungs, compressor loops, and air manifolds.
- Solid Brass Architecture: Naturally fights off rust and environmental corrosion to keep your receiver threads clean and functional over years of service.
- Vibration Resistant Fit: Built to maintain an absolute airtight seal under severe off-road, heavy-duty commercial, and automotive chassis strain.
- Streamlined Low Profile: Compact, block-style hex head easily slips into tight spaces between crowded fittings, brackets, or frame rails.
- Versatile Application: An ideal port-blocking solution for custom Jeep, RAM, Ford, and GM vehicle-specific air tank configurations.
THE VERDICT:The definitive professional finish for premium threaded plumbing. The Model 50040 provides a rugged, clean, and airtight solution to confidently plug any empty 1/4" port on your air tanks or manifolds.
What's Included in the Box
- Hex Tank Plug: One (1) Model 50040 1/4" Male NPT Solid Brass Hex Plug fitting.
🔴 PRO TIP: Eliminate phantom leaks and system bleed-downs. When winding this male hex adapter into your tank or manifold ports, avoid over-torqueing to protect the brass receiver walls from stress fractures. Always apply a few drops of liquid anaerobic thread sealant compound like our genuine Kleinn JUICE across the male thread leads to form a permanent, vibration-resistant structural seal.
