铁氟龙耦合器夹（22毫米管），用于消声器 - 60毫米长度
These are simple teflon connectors with spring clamps. They work well, and at this price, there's no need to go anywhere else to get these quality connectors.
This item is complete useless. The inner size of the clamps is 22 mm the same as the inner size of the tube, the outside size is 27mm. I have tryed to open the clamps far enough to get the tube in, it did n't work, the clamp became oval. HK please provide correct clamps for this item,........
separate they can be used, but not together,...
