With oetiker clamps there is no substitute for clamps. I figured I could get away with using needle nose and grooved pliers, aka water pump pliers, adjustable pliers, tongue and groove pliers, elbow pliers, multi-grippers, faucet or pipe wrenches, gland pliers, and channel locks (e.g. Channellock). branded pliers) but I was able to achieve the proper sharp clamp required with Oetiker style clamps. I prefer models with front and side clips for tight spaces.
