#12 Ensure Hose Clamps (4pk)

The #12 Ensure Hose Clamps (4pk) by XRP-XTREME RACING PROD. are precision spring clamps engineered for high-performance fuel, coolant, and fluid line management in modified and racing vehicles. Designed for AN12 hose fittings, this four-pack addresses a critical need in engine bay plumbing—secure, vibration-resistant fastening that withstands extreme temperatures and pressure cycling. Whether you're building a turbocharged stroker, upgrading fuel delivery on a carbureted classic, or assembling a competition platform, reliable hose clamps are non-negotiable for safety and longevity.

Constructed from steel with a natural finish, the Ensure spring clamp design delivers consistent clamping force without the slip associated with worm-gear alternatives. The spring-loaded mechanism maintains tension across thermal expansion and contraction cycles, reducing the risk of leaks or disconnection—critical when running upgraded fuel systems or custom coolant loops at elevated boost pressures. The compact 2.7 x 1.4 x 3.65 inch profile allows tight installation in congested engine compartments, while the steel construction resists corrosion and maintains clamp integrity under sustained vibration from high-RPM operation.

Mechanics and engine builders working on fuel-injected conversions, nitrous systems, and forced-induction platforms benefit most from the consistency and reliability of a matched set. The four-pack is ideal for a single complete fuel system retrofit or distribution across multiple cooling circuits on a dual-radiator setup. Installation requires only hand-tightening; no special tools needed. Compatibility extends to any system using AN12 hose couplers, making these clamps a universal shop essential for both street and track applications.
