Tube End 1/2-20 LH 1-1/8in x .058in

The Tube End 1/2-20 LH 1-1/8in x .058in by Allstar Performance is a precision threading component engineered for high-vibration automotive and powersports applications where secure tube connections are mission-critical. This left-hand threaded fitting serves fabricators, race mechanics, and restoration specialists who demand reliable, repeatable assembly in suspension systems, exhaust installations, and hydraulic line routing. The product exists to eliminate guesswork in tubing termination, ensuring proper load transfer and leak-free performance under dynamic conditions.

This tube end features a 1/2-20 left-hand thread specification, a standard pitch that pairs with common tube and fitting ecosystems in motorsports and industrial hydraulics. The 1-1/8 inch outer diameter and .058 inch wall thickness provide structural rigidity while remaining lightweight at 0.31 lbs—critical for applications where unsprung or rotating mass directly impacts handling and fuel efficiency. Left-hand threading prevents accidental loosening in rotating assemblies and counterclockwise-motion situations, a proven design principle used across aviation, racing, and military equipment. The compact 4 x 1.2 x 7.05 inch footprint integrates seamlessly into tight engine bays and frame rails without compromising accessibility for maintenance or inspection.

Professional mechanics, fabrication shops, and off-road builders benefit most from this component when constructing custom suspension links, fuel-system plumbing, or brake line assemblies that demand corrosion resistance and vibration dampening. Installation requires standard tube-end tooling and torque protocols; the 1/2-20 LH specification ensures compatibility with Allstar Performance's ecosystem of tube adapters, elbows, and manifold blocks. Verify thread direction before assembly—left-hand threading is directionally specific and will not interface with standard right-hand fittings. This component performs reliably across temperature extremes and is ideal for vehicles operating in harsh environments, competitive racing, or heavy-duty work applications.
