Hose Clamp, German 304SS, 9 x 70-90mm
$0.65
per EACH (USD)Stainless Worm-Drive Hose Clamp, 70-90 mm, 9 mm Band
Smooth-band (German-style) 304 stainless hose clamp for hose from 70 to 90 mm (2.76-3.54") outside diameter.
The Racetronix GCLMPSS-90 is a worm-drive hose clamp with a smooth, unperforated 304 stainless band. The screw drives against the band's pressed thread instead of through slots, so the band stays flat against the hose, and its rolled edges will not cut into it. It is the clamp to use on rubber and Viton (FKM) hose.
Key features
- Clamping range: 70-90 mm (2.76-3.54") outside diameter of the hose.
- Smooth band, 9 mm wide and 0.65 mm thick, with rolled edges that will not cut into the hose.
- 304 stainless steel band for excellent corrosion resistance.
- Adjustment screw: 7 mm (9/32") slotted head.
- Re-usable and adjustable.
Choosing the size
Measure the outside diameter of the hose after it is pushed onto the barb or tube. Choose a clamp whose range covers that size, ideally with the size near the middle of the range so the band has room to tighten.
Use worm-drive clamps on rubber or Viton (FKM) hose, such as our SAE 30R10 submersible hose (RH-30R1014, RH-30R1056, RH-30R1038). On corrugated nylon fuel tube they bind, pinch and cut in: use ear clamps there instead.
How to install
- Open the clamp fully and slip it over the hose before you fit the hose to the barb.
- Push the hose fully onto the barb. Position the clamp just behind the barb's raised ridge, not on the end of the hose.
- Tighten the screw until the hose is snug and sealed. Do not overtighten: crushing the hose can make it leak or crack.
Re-check clamps on new hose after the first heat cycle; rubber hose can relax slightly.

Frequently asked questions
What is a German-style clamp?
The band is smooth instead of perforated: the screw engages pressed-in threads rather than slots. The band stays flat, clamps more evenly and does not chew the hose surface.
Can I use it on nylon fuel tube?
No. On corrugated nylon tube a worm-drive band binds, pinches and can cut in. Use ear clamps on nylon tube.
Which size do I need?
Measure the hose outside diameter fitted on the barb, and choose the clamp whose range covers it with the size near the middle.
