MODEL 51414F: 1/4" FEMALE NPT STRAIGHT COMPRESSION FITTING FOR 1/4" O.D. TUBE

HIGH-FLOW FEMALE INLINE COMPRESSOR LEAD EXTENSION

Bridge the gap between distant pneumatic hardware mounts with the premium Kleinn Model 51414F Straight Female Compression Fitting. Precision-machined for seamless inline plumbing, this commercial-grade hardware component is engineered to provide an airtight mechanical transition between a 1/4" NPT male lead and 1/4" Outside Diameter (O.D.) air tubing. It serves as an indispensable tool for custom onboard air configurations where factory hose runs fall short of your storage reservoir destination.

EXTEND YOUR COMPRESSOR'S REACH WITH TOTAL RELIABILITY

The Model 51414F is uniquely useful for extending a heavy-duty air compressor's physical layout path. If your compressor is mounted in a remote chassis location where the factory-equipped metal leader hose cannot physically reach the air tank, this fitting allows you to adapt the 1/4" Male NPT end of that leader hose directly to a flexible 1/4" O.D. plastic air line. Built to easily absorb high temperatures and aggressive automotive vibrations, it delivers the ultimate flexibility to complete complex layouts regardless of distance.

Why Choose the 51414F Female Compression Fitting?

  • Compressor Line Extension: Effortlessly extends the reach of factory compressor leader hoses when mounting distances to the reservoir tank are exceeded.
  • Precision Female Threads: Standard 1/4" Female NPT threads provide a deep, direct, and unyielding connection to male pneumatic lead ends.
  • Leak-Proof Mechanical Grip: Features a heavy-duty compression nut and ferrule system that locks onto 1/4" O.D. high-pressure tubing without specialized flaring tools.
  • Industrial Temperature Resilience: Precision-machined construction easily withstands the high extreme heat and continuous vibration found in automotive pneumatic loops.

THE VERDICT: The definitive female adapter for custom-extended plumbing runs. The Model 51414F blends a robust mechanical compression sleeve with a clean, straight inline profile to guarantee your high-pressure lines adapt flawlessly to long-reach chassis configurations.

What's Included in the Box

  • Compression Fitting: One (1) Model 51414F Straight 1/4" Female NPT to 1/4" O.D. Tube adapter body.
  • Locking Hardware: One (1) pre-matched compression nut and sleeve ferrule kit.

🔴 PRO TIP: Ensure a permanent, zero-leak lock on your air lines. Before snugging down the compression nut with your standard service wrenches, use a dedicated pneumatic hose cutter to ensure your 1/4" O.D. high-pressure line is sliced completely square and smooth. Always add a few drops of liquid anaerobic compound like our genuine Kleinn JUICE to your mating Male NPT threads to completely insulate against slow, phantom pressure leaks.
