Description

3/8" Hose Bulkhead Fitting for Air Launcher Lines (10-Pack)

Give your custom build, race car, or street machine the professional finish it deserves. Designed to provide a clean, secure, and leak-free method for routing air launcher lines, nylon hoses, or cables, this 3/8" Hose Bulkhead Fitting is the ultimate pass-through solution for rear valences, firewalls, and exterior body panels.

When routing lines through metal or composite panels, friction and sharp edges can easily cause devastating wear, leaks, or failure. This fitting creates a rigid, fixed point that tightly seals the passage—protecting your 3/8" hose from abrasive damage while keeping the elements outside where they belong.

Key Features:

  • Zero-Leak Protection: Eliminates the risk of hose chaffing, air leaks, or body-panel wear.

  • Professional Aesthetic: Replaces sloppy pass-through holes with a flush, rugged, and clean exterior appearance.

  • Rock-Solid Connection: Includes a heavy-duty 1" hex locking nut and internal tooth washer to guarantee the fitting will never vibrate loose.

  • Built to Last: Durable polymer and corrosion-resistant steel components built to withstand racing, automotive, and industrial environments.

  • Value 10-Pack: Ensure you have enough for multiple routing projects, launcher assemblies, or service replacements.
