304 Stainless steel worm gear clamp consists of a stainless steel band, housing, and screw..
They can adjust the miniature size for fitting small hoses. A worm gear mechanism adjusts the clamp's diameter to precisely apply sealing pressure..
The slotted screw allows installation using a blade screwdriver, nut driver, or socket wrench. 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..
Worm Gear Hose Clamps are flexible and ductile with wide adjustable size about 1/2'' - 3/4'' (13-19mm). Fit for hose outside diameter 1/2'' - 3/4'' (13-19mm)..
You Can Adjust The Size According To Demand, Worm Friction Is Small, Lock Secure And Tight..

8 (200mm) f/5 optical design gives excellent wide field views.
Parabolic primary mirror minimizes spherical aberration to produce a better image.
Integer gear ratios and permanently programmable Periodic Error Correction eliminates recurring track errors from the worm gear..
New motors offer improved tracking performance & provide more power to overcome load imbalances.
Updated industrial design offers more rigidity, less flexure and improved aesthetics.
