MVP's constant tension hose clamps are a superior form of clamps
designed to eliminate "cold flow" leaks with their Belleville spring
mechanism. This allows the clamp to automatically expand and contract as the engine temperature increases and decreases. They also feature an extended inner liner which protects softer hoses such as silicone from the worm gear serrations. The 5/8" band, housing and screw are made from stainless steel.
Beware of questionable Chinese aftermarket clamps! We spent several years searching for a reliable, high quality supplier, not just the lowest bidder. Our source has 80% of the commercial truck OEM hose clamp business in India, and has been in business for over 50 years. We could import these from China for half what we buy them here for, but they would not be the same quality as these (the Chinese clamps we inspected often had rough edges, weaker springs, questionable stainless grades, inability to maintain torque, poor spot welds, etc.) Our MVP clamps provide a great value: OEM quality at a good price.
