Product Description

The Precision Brand smooth band metric worm gear clamp has a stainless steel band and housing, and a plated steel screw, and is appropriate for use in critical hose connections. A worm gear mechanism adjusts the clamp’s diameter to precisely apply sealing pressure. The 9 mm band has a smooth form that helps provide even pressure around the hose, and an efficient seal at low torque. The pressed, non-perforated worm drive teeth and rounded, raised band edges help prevent damage to the hose. The band, housing and screw are made of stainless steel that conforms to the Society of Automotive Engineers (SAE) 400 series standard and provides resistance to corrosion wear. The slotted, 6mm hex-head screw allows installation using a blade screwdriver, nut driver, or socket wrench. The screw is made of carbon steel that is zinc-plated for resistance to rust.

Hose clamps attach hoses to fittings to prevent flow leakage. They come in a variety of designs and distribute uniform pressure over the circumference of hoses to bind them to fittings. Hose clamps are suitable for a large number of industries, and commonly used in industrial, electronic, and automotive applications.

Precision Brand Products manufactures products such as hose clamps, shims, keystock, threaded rods, punch and die sets, and wire. The company, founded in 1946 and headquartered in Downers Grove, IL, meets International Organization for Standardization (ISO) standard 9001.

Great price on quality clamps. Ive seen these on German imports. My previa has some funky band clamps that are single use and hard to get. Figured I'd use these as replacements. They work perfectly. 360 compression. Tightens properly. Stamped with Made in Germany, so you know they're good quality. Rubber won't deform like with the worm gear clamps. I painted them with rust prevention paint for added measure.

perfect match for BMW automobiles...

Reviewed in the United States on October 30, 2013

Verified Purchase

I fix BMW cars as a weekend hobby. I maintain a small fleet of 7 BMWs that belong to friends and neighbors in addition to 2 of my own and the occasional referral. Being an enthusiast, I'm very meticulous about using high quality parts, I always clean every part before I put it back on, and if I modify anything I want it to look like it came from the factory that way. To that end, I've occasionally had to replace hose clamps due to someone else damaging the screw head or I've added hose clamps for some modifications. I prefer to have hose clamps that "match" and of similar quality as the factory OEM hose clamps. These hose clamps from Precision Brand Products are a perfect match to the factory OEM hose clamps minus the "BMW" logo being stamped on the band. In fact, they are stamped "Made in Germany" so I speculate they might be manufactured by the same supplier that BMW must use at their factory.

Beyond satisfying the enthusiast OCD needs I have, they are of high quality construction. The edges of the band have a smooth "lip" so they don't cut into the hose. The worm drive screw head can be turned with a slotted screwdriver or a 6mm nut driver or socket. This is particularly helpful if the hose clamp is positioned in a hard to reach location, it's very helpful to be able to reach them with a variety of attachments and extensions connected to a 1/4-inch drive ratchet.

Good quality and better hose clamp design

Reviewed in the United States on November 25, 2019

Verified Purchase

This style clamp is commonly used on German cars. I prefer this design because the edges are beveled and there are no slots in clamp for screw drive. The beveled edges and absence of slots prevent damage to the hose when tightening the clamp.
These clamps are also narrower than standard hose clamps while retaining the same clamping force.

OEM/OES for BMW hose clamps

Reviewed in the United States on December 1, 2014

Verified Purchase

Bottom Line Up front: These Hose clamps are made by Norma. Norma is the main supplier/manufacturer (OEM/OES) to BMW for all of their hose clamps requirement.

Pros:
1) Made by Norma, OEM/OES for BMW hose Clamps
2) Made in Germany
3) Smooth Band. Will not eat/bite into rubber hose and thus destroying it
4) Excellent Rust Protection
5) High Quality
6) 5x cheaper than buying the BMW hose clamps from BMW dealership. The only difference between these clamps and the BMW clamps are the absence or presence of the fancy "BMW" logo. Again, both (BMW and Precision Brand Products) are made by Norma.

I hope you find this review useful. I am trying to share and contribute to the community. If you find my review helpful then please give me a positive feedback/review.

Used to update the hose connections on my truck. Much cleaner look than the standard skeletonized versions of these clamps. The combination head with slot and hex head gives options for installation in tight areas. Does not seem to be as strong as the cheaper models, but more than sufficient to hold tightly,

Reviewed in the United States on July 23, 2014

Verified Purchase

The quality on these clamps is outstanding. They have a nice rolled edge so they don't bite in to the hose, and the screw holds very tight. I tightened mine up with a 6mm wrench and did a couple tests since I bought 6 packs in various sizes.

You'd have to really tighten beyond any reasonable amount of clamping pressure to strip these out. If you're having to clamp that tight, you probably have another problem going on.

They are also German made, which was a very nice surprise.

That said, my use for these is automotive. I saw another review about using these on air lines, based on that, I probably wouldn't get these if that was my intention for use.

Works perfectly, and at an awesome price as well. I love the ease with which these installed to keep my silicone tubing from slipping off of some camlocks. If you're making hoses for your homebrew (or anything) these are an amazing addition that won't tear up your tubing. And who want's torn up tubing? Not me.
