2-Ear Pinch Clamps

Description & Features

Application	Especially suited for industrial use and with heavy vibrating equipment. These clamps are installed on air, fluid, gas and steam lines. The one piece design offers a positive, tamper-proof seal without damaging the hose.
Installation	While both ears must be closed, 2-Ear clamps are best installed when one ear is closed all the way first. The second ear is then closed so that the first ear opens slightly (gap to be approximately 1/16 inch). This builds a resilient strength into the clamp in a spring-like action to hold against pressure, vibration and hose shrinkage due to temperature changes or aging. (If both ears can be closed all the way, the clamp size selected is probably too big and the next smaller clamp should be used).
Note	To insure a proper grip, Oetiker clamps should be installed with either Oetiker Pincers or a similar style of pincer approved by Oetiker, Inc.

For the best grip, you'll want to use Oetiker Pincers or a similar style of pincer that's been approved by Oetiker, Inc.
