Hose Clamp part number??

[Tiger75]

Anybody got a part number for a fuel injection type hose clamp to be used for the 12mm x19 mm vacuum hose from intake to brake booster on a 74 Tii? It is also called a NORMA clamp. I am using worm gear clamps now except for one orginal type and there is no part number on it or on Real OEM or MAX.

Thanks

07129952107 is less than $1 list price from BMW

Same part is used on many brake vacuum hoses from the Neu Klasse thru E46 models at least.

You just did not search well enough, it's listed on the online catalogs & the ETK CD.

"Norma" clamps usually refer to the standard German style worm gear radiator hose clamps, that are a bit narrower than the US aftermarket style. They are popular due to being well made with a good rolled edge design that does not cut the hose when installed properly. Where they (screw gear type) fall short is they cannot compensate for cold flow of the hose rubber that can make the clamp loosen. The Norma brand was used on some Domestic car's radiator hoses with an internal assist spring band to compensate for the shrinking hose diameter. The fuel injection hose clamp & the Oetiker do a much better job, the Oetiker being first choice where you don't have to disturb it routinely for maintainence, as they have enough springiness in them to expand & contract quite a bit.

I am changing out the booster hose on my 73tii and the Gemi brand hose clamps are in pretty good shape but slightly corroded.

Clamp removed from the 73 yesterday

I have found these Ideal brand fuel injection clamps at Advanced Auto Parts, but they are not exactly the same.

John, have a found a source for NORMA clamps?

WURTH furnishes Norma clamps.

[BillWilliams]

Thanks but only the smaller sizes. I have not been able to get them from Wurth big enough for he radiator or the tii intake boot

If you know other wise, let me know

Bill, in our area you can get these at Olympus Imported Auto Parts, and probably NAPA. Don't know what sizes are available.

I tried the NAPA, need to call the boys at Olympus

I believe I visited the Olympus store on Eisenhower Avenue last year and they didn't have any of those style clamps (only regular worm gear ones) and they also didn't have the right size metric fuel hoses.

I then went to BMW of Arlington parts dept. and they also didn't have the hose and clamps in stock. The counter guy brought out a bunch of different hoses, but none were for our vintage cars.

While having our MB serviced at the dealership last year, I asked the parts guy about their hose clamps. He brought out the standard worm gear ones. When I told him it was for high pressure fuel lines, he said the smooth, standard ones is all they have ever purchased.

Edit = ipd (Volvo place) has the 17mm ones

I went round and round on this last year and could only find the smaller ones. Jim, that site also looks like they do not have the larger ones

in Chantilly in the fall. They walked me into the back and let me pick from the bins.

I was trying to buy the Euro worm-type with the roundel on them from the BMW dealer and the parts guy said "save your money and get them from the imports parts place." He said they were junk compared to Wurth, Zebra, or Norma and overpriced, even with wholesale pricing.

[jgerock]

Went up to Advanced Auto a few hours ago. They didn't have any of the Ideal "norma" clamps larger than 16mm. Crap.

Wonder if I could just bead blast the old ones and paint them silver (although we don't have a basket for our blast booth at work).

Just browsed thru the diagrams on Max's site for both early 2002tii and 2000tii:

Hose clamp for the plastic U-tubes: 07129952123 @ $ 2.12 each

Looks like 53-60mm diameter

[BillWilliams]

Those are the standard screw type, not the NORMA ones

I figured as much. I also looked for that little strainer on the inlet of the KF pump (NK, '02 and E12 520i). No luck yet.
