Consisting of a seal ring that utilizes a soft and metal to metal seal, the Safety Iron is used to take the place of a traditional wing nut union connections. An upper clamp along the bolts and the lower thread clamp are included in it. The slipping of the metal ring and the rubber steal is free in the narrow flange end connection.
Meanwhile, the sealing is achieved through the rubber seal's end crush and the mental contact from the force of the clamp.
Compared to the traditional hammer union connections, this safety iron connecting system is much better and safer.
