The Micro Matic 898 is a professional-grade 10.0mm stepless ear clamp (Oetiker style), engineered to provide a permanent, 360-degree leak-proof seal on draft beer system lines. This specific clamp is sized for use with 1/4" I.D. polyethylene (LLDPE) tubing, which is commonly used for gas distribution and specialized beverage lines. Unlike traditional worm-gear clamps that can create "flat spots" or pinch the hose, the stepless design ensures uniform compression around the entire circumference of the tubing. Constructed from high-quality stainless steel, the 896 is highly resistant to corrosion and is designed to maintain its tension indefinitely, even in the high-vibration and moisture-heavy environments of a commercial walk-in cooler.

  • Model Number: 898 (Oetiker Size 10.0)
  • Tubing Compatibility: Designed for 1/4" I.D. Polyethylene (Poly) and thin-walled 3/16" I.D. Vinyl tubing
  • Clamp Type: Stepless Ear Clamp (Requires a pincer tool for installation)
  • Material: 304 Stainless Steel for maximum corrosion resistance and flavor neutrality
  • Design: 360° Stepless design eliminates gaps and prevents "cold flow" leaks
  • Safety: Provides a tamper-proof, permanent connection that won't loosen over time
  • Application: Ideal for CO2 gas lines, air lines, and high-pressure beverage connections
  • Durability: Engineered to withstand the rigors of commercial draft beer installations
Technician's Note: The 10.0mm clamp (898) is the precision choice for 1/4" poly gas lines. Because polyethylene is more rigid than vinyl, it requires a clamp that provides perfectly even pressure to seat the tubing against the barb. For proper installation, you must use a pincer tool (like the Micro Matic MP-039). Once crimped, these clamps cannot be loosened—they must be nipped off for removal—ensuring that your gas system remains airtight and your CO2 tanks don't empty prematurely due to slow leaks.
