The Kugel Komponents 3/8" Single Line Clamps (12-Pack) offer a clean, professional, and secure solution for routing heavy-duty plumbing on your vehicle. Manufactured to show-quality standards, these clamps eliminate the messy look of generic rubber-insulated p-clamps or plastic zip ties, making them a favorite for securing larger hard lines along frame rails, firewalls, and undercarriages.
Premium Construction
-
Heavy-Gauge Stainless Steel: The clamps are stamped from high-quality, corrosion-resistant stainless steel. This ensures they will not rust, tarnish, or degrade over time, even when exposed to harsh road debris, moisture, or under-car environments.
-
3/8" Hard Line Profile: Specifically sized to snugly hold 3/8" hard lines without pinching or crushing the tubing. This size is the industry standard for high-volume EFI or carbureted fuel feed lines, modern transmission cooler lines, and heater return lines.
Precision Sizing and Versatility
Kugel Komponents sizes these clamps by their exact Inside Diameter (I.D.), which directly matches the Outside Diameter (O.D.) of the line you need to clamp. These clamps are designed to fasten your lines flush against an object like a frame rail, fender panel, or firewall. Whatever the O.D. of your line, hose, or cable is—that is the exact clamp size you need.
Complete Hardware Kit
Every package is ready for a clean installation and includes:
The included low-profile button head screws offer a sleek, flush appearance once torqued down, requiring only a standard Allen wrench for installation.

Installation Tip
To install these clamps into a vehicle frame or floor pan, you will need to drill and tap the mounting holes to match the included 10/32 thread hardware. For high-vibration areas (such as along the frame rails), applying a small drop of blue medium-strength threadlocker to the screws is highly recommended to keep your plumbing setup securely locked down.
