Upgrade & Restore Your Tire Changer's Pneumatic Air Flow

The 8000372 Brass 90-Degree Street Elbow (Ell) Fitting is a premium, direct-replacement pneumatic connector engineered for the foot pedal control valve assemblies of professional tire changers. It features a 1/4" NPT male thread on one end and a 1/4" NPT female thread on the other, allowing you to route high-pressure air supply lines at a tight 90-degree angle inside the base cabinet of your machine.

Daily pedal operations and high-volume shop vibrations can stress rigid air lines, leading to microscopic brass fatigue or micro-cracks that slow down air delivery. This 90-degree street ell prevents polyurethane tubing from bending, pinching, or kinking under the foot pedal tray, ensuring a constant, un-throttled air volume (up to 175 PSI) to your tabletop clamping cylinders.

Machine Location:

This fitting installs directly on the Pneumatic Foot Pedal Control Valve Assembly inside the base cabinet of the tire changer. It threads directly into the aluminum inlet/outlet ports of the 4-way pedal valves, allowing tight, 90-degree routing of the main air supply lines.

Key Features & Specifications

  • Premium Brass Construction: Machined from high-strength, corrosion-resistant brass to withstand demanding garage environments and constant moisture from air compressors.
  • Port Configuration: 1/4" NPT Male to 1/4" NPT Female.
  • 90-Degree Profile: Enables clean, low-profile routing inside the foot pedal cabinet to prevent mechanical interference with pedal linkages.
  • High-Pressure Seal: Tapered NPT threads provide a secure, leak-proof seal under standard operational pressures of 110 – 175 PSI.

🔧 Pro Installer Tip:

When threading this brass street elbow into the aluminum body of your foot pedal valve (such as 4-way valve #8184878 or #8184369), never over-torque the fitting! Brass is a softer metal, and over-tightening can easily strip the threads or crack the valve body ports. Apply a thin, even coat of liquid thread sealant (or 2-3 wraps of Teflon tape) and thread it in until hand-tight, then snug it down 1 to 1.5 additional turns with a wrench to align the 90-degree outlet in the desired direction.
