(888) 312-8812 Login SignupThe Tectran DOT AB SW is a pneumatic component used to route and control air flow in trailer and tractor systems that rely on DOT-approved hardware. Its construction promotes stable air movement through circuits such as brakes, suspension controls, or auxiliary air-powered components. This part fits naturally into everyday fleet operation, where air lines experience constant vibration and repeated pressure cycles. Moreover, its resistance to corrosion from road spray and de-icing chemicals extends its service life in northern climates. If an air system needs consistent transfer of supply air through DOT-compliant fittings, the Tectran 85511 delivers the right performance for ongoing use.
