Jinghong factory produces 304 stainless steel single-ear stepless clamps, which are clamps with one ear and a smooth inner ring without steps. By clamping the ear with special clamp pliers, the clamp tightens, firmly securing the hose to the pipe joint. 304 stainless steel can be used in various occasions.
The inner wall of ordinary worm gear clamps has threaded joints. After tightening, those joints will press a mark on the hose, and over time, the hose is prone to cracking at that spot. The inner wall of the single-lug stepless clamp is flat, with uniform stress applied to the entire circumference, so the hose will not be locally damaged by constriction.
The structure of a single ear is simpler than that of a double ear, and the force required for tightening is less. For double ears, you need to clamp twice, while for single ears, once is enough. The installation speed is fast, making it suitable for batch assembly. Moreover, the ears of a single ear are relatively short, so after installation, the protrusion is small, and they won't touch the adjacent parts in a compact space.

The inner ring is smooth, preventing damage to the hose: The inner wall of the stepless design is a smooth arc, without any joint steps. After locking, the entire circumference is evenly stressed, ensuring the hose is not locally pinched and left with deep marks. The threaded joint of the worm clamp will leave a mark on the hose, which may crack over time. However, this does not happen with the single-lug stepless design.
Single ear tightening is fast, and batch assembly saves time: one ear, one clip, and it's done. Workers on the assembly line use clamp pliers to clip one ear at a time, which is several times faster than tightening worm gear clamps. The ears are short, and after assembly, they protrude slightly, causing no interference in tight spaces.
