TUBING (P/N b-44-3) - New Surplus

Tygon B-44-3 is flexible thermoplastic tubing designed for aircraft instrumentation and service lines. The clear, beverage-grade material bends easily for routing pitot-static and vacuum circuits in non-fuel applications. Part b-44-3 connects to barbed fittings for secure, leak-free instrument plumbing.

Commonly used in experimental and homebuilt aircraft where standard rigid tubing routing is impractical. Not FAA-approved for fuel service. Install per AC 43.13-1B guidance and your aircraft documentation.
