AUTOMANN Air Hose Assy ½" ID x 3/8" NPT x 22" Part No: 177.7822

The AUTOMANN 177.7822 air hose assembly was developed to support heavy-duty pneumatic systems with a precise 22″ length, ½″ inner diameter, and 3/8″ NPT threaded ends (one fixed, one swivel). The hose is constructed from flexible, abrasion-resistant rubber, designed to resist wear under vibration, thermal cycling, and exposure to road chemicals. It meets SAE J1402 and DOT FMVSS 106 specifications, reflecting its compliance with standard safety and performance criteria. The swivel end allows better alignment and reduces torque stress on fittings, while the fixed end ensures a rigid, leak-tight interface. As a replacement for aging or damaged OEM hose assemblies, 177.7822 restores reliable airflow and pressure control in air brake and pneumatic circuits. Wofford Truck Parts offers this assembly as a dependable, specification-compliant component for trucks and trailers in service.
