Oetiker patented "stepless" spring clamps eliminate thermal cycling
maintaining a constant clamping tension across coolant temperature swings,
and ensure 360° clamping with the "tongue-in-groove" design. This clamp
design also virtually eliminates hose damage caused by over-tightening
(often necessary with conventional clamps to control cold seepage).
The larger hoses (on a 94 NA Diesel) require 55, 60, and 65mm clamps cost
about $3.00 each. "Stepless" spring clamps are limited in their adjustment
range so careful selection is required.
