Blind Stops made of Polyamide 6 are used wherever threads previously cut must be closed for preventing dust, dirt and foreign matters from entering the enclosure or equipment. O rings of Neoprene should be mounted on the threaded part to get the IP 68 protection. They are also available in Hexagonal shape and longer thread size.
They are available in Pg Thread in Polyamide (Circular), Metric Thread in Polyamide (Circular), and Metric Thread in Polyamide (Hexagonal)
