The Kugel Komponents 3/16" x 3/8" Combo Double Line Clamps (6-Pack) offer a specialized, space-saving plumbing solution for your vehicle. Instead of routing lines separately, these dual-opening clamps allow you to neatly run two different-sized lines side-by-side using a single mounting point, giving your frame rails, firewalls, or undercarriages a highly organized, show-quality finish.
The Perfect Brake & Fuel Line Combo
The 3/16" x 3/8" staggered layout is custom-tailored for the most common routing configuration in automotive builds:
-
3/16" Opening: Perfectly sized to hold a standard 3/16" O.D. hard brake line.
-
3/8" Opening: Perfectly sized to secure a 3/8" O.D. hard fuel line (commonly used for high-volume carburetor feeds or EFI supply lines) or a modern transmission cooler line.
By locking both lines into a single sturdy clamp, you prevent the lines from rubbing against one another, eliminating metal-to-metal friction and harmonic rattling.
Precision Sizing and Versatility
Kugel Komponents sizes these clamps by their exact Inside Diameter (I.D.), which directly corresponds to the Outside Diameter (O.D.) of the lines you need to secure. Whatever the total O.D. of your line, hose, or cable is—that is the clamp size required.

Installation Tip
To mount these dual-line clamps, you will need to drill and tap your chosen mounting surface for a 10/32 thread. Because you are securing two fluid lines under a single fastener, applying a drop of medium-strength blue threadlocker to each screw is highly recommended to protect against road vibrations and ensure your plumbing remains safely locked down.
