It accepts 1\/4-inch OD tubing on each tube port and threads into a 1\/8-inch NPTF female port. Rated to 250 psi maximum working pressure, this fitting handles temperatures from -40 degrees F to 200 degrees F. The nitrile O-ring construction ensures a reliable seal under pressure cycling. It carries D.O.T. FMVSS571.106 certification, making it a legitimate air brake fitting for commercial vehicle and fleet applications. Installation requires no tools on the tube side — tubing seats and locks with a straight push.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in D.O.T.-rated air brake systems, pneumatic control lines, and compressed air distribution plumbing where a tube-to-female-NPT inline connection is needed. Typical applications include commercial truck air brake circuits, industrial pneumatic panels, and HVAC or refrigeration control line assemblies where push-to-connect convenience and compliance with SAE J2494 and SAE J2494-3 standards are required. Its compact overall length of 0.56 inches makes it well suited for tight routing runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect tube ports accept 1\/4-inch OD tubing — no ferrules or compression sleeves required\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch NPTF female thread with D.O.T. air brake certification per FMVSS571.106\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 200 degrees F\u003c\/li\u003e\n  \u003cli\u003eNitrile O-ring seal resists petroleum-based fluids and compressor oils\u003c\/li\u003e\n  \u003cli\u003eCompliant with SAE J2494 and SAE J2494-3 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-inch OD tubing in D.O.T.-rated air brake systems and pneumatic circuits requiring a 1\/8-inch NPTF female port connection.

The NPTF threads should be installed by a qualified technician familiar with D.O.T. air brake component requirements and applicable SAE standards. Apply thread sealant compatible with the system fluid — do not over-torque the threaded port connection. Ensure tubing is cut square and free of burrs before inserting into the push-to-connect ports to achieve a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Tube x FNPT x Tube x Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inches NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Nitrile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: D.O.T.
