With it’s premium stainless steel construction and 4-3/8-Inch clamping capacity, this clamp will resist scale and will not rust - delivering a tight and optimal seal under a variety of environmental conditions.Easy-To-UseThese hose clamps feature an easy-to-turn blue key (knob) made from a strong and durable polymer. The key is designed to make the securing and un-fastening of the hose much easier, by hand and without the use of any tools. This eliminates the knuckle busting associated with flat head screw drivers or tiny socket wrenches.True Seal ConnectionThe clamps have an integral bridge component that steps over the tubing’s helical reinforcement, delivering a direct transfer of force to the connection, which helps eliminate hose detachment and pressure loss from leakage.SpecificationsMaterial: Stainless SteelClamping Capacity: 3-1/2” 4-3/8”Clamp Width: 3/8”POWERTEC is a US basedmanufacturer of high quality woodworking machines, wood work accessories, and a wide assortment of OEM replacement parts.

These work much better than regular worm gear clamps for attaching dust collection hoses to machines. They are quick to use and provide a very strong connection. They can easily be used in place of expensive quick connect systems.

It definitely fits and does the job. The turn key is fairly stiff and takes a good bit of effort to turn.

These are great! Perfect size and easy to tighten down without the hassle of using a screwdriver and trying to tighten a screw while laying over 2x6 in an attic installing a bathroom fan vent. These are super convenient to have. I was just the supervisor 😉 but also tightened one down as my husband worked. Great product and price.

The thumb turns are a little weak and really close to the band, so it's hard to get your fingers around them. The plastic on the thumb turns is thin, so it will likely break over time.

These clamps are definitely better quality than the clamps that come standard with some dust collection parts. The standard clamps often slip, skip teeth, or just break open when you try to get them tight. These clamps hold tightly, and are easy to operate with the thumbscrew.

Used the clamps for my home made gutter leaf vacuum system to attach 4" clear flex tubing.

I purchased these for use with my dust collector. I had previously used regular hose clamps. Was initially worries at how thin these were, but they turned out to be quite sturdy and adjusts perfectly to use on my table saw, planer, jointer and router table. I’m very happy with them including the price.

Work great. They are not Ä· to the coil pvc pipe though. They do stay tight.
