Technical Data Sheet Connecting Technology

Tongue-in-groove design Interlock Narrow band: concentrates transmission of clamping force, less weight Stepless over 360°: uniform compression or uniform surface pressure Clamp ear: compensates for component tolerances, adjustable surface pressure Dimple: increases clamping force, spring-effect compensates for changes in diameter due to thermal expansion Burr-free strip edges: reduced risk of damage to parts being clamped Stepless® Ear Clamps Product Group 117 & 167 Material PG 117 Galvanized or zinc-plated steel band PG 167 Stainless Steel, Material no. 1.4301/UNS S30400 Optional...

Note: the above sketch shows the appearance of a closed “ear” (s’); it does not necessarily indicate an effective closed assembly. The following applies as a guideline: To determine the correct clamp diameter, push the hose onto the attaching material, (e.g. the nipple), and then measure the outer diameter of the hose. The value of the outer diameter must be slightly above the average value of the diameter range of the clamp to be selected. A clamp can only be considered adequately closed when the ear width (s) has been reduced by at least 40%, and the correct closing force was used for...

PEX connecting solutions for markets compliant with Standard ASTM1 F877/F2098 PG 167 PEX (conform to ASTM F 877/2098) The specified clamps are suitable for fast and secure connections of PEX 2 pipes in the plumbing field. The clamp design ensures tamper detection. The clamp sizes are solely intended for PEX applications with corresponding inch sizes. The robust interlock design, specifically developed for PEX applications leads to even higher radial loads of the clamp.
