Model RT4000 coupon insertion system is a retractable unit commonly used in field and plant applications. A specially designed packing gland is used to insert or retract a coupon from a pressurized system without a process shutdown. The insertion system is designed to mount onto a 1" piping system, but can easily be adapted to fit your specific requirements. The system consists of an insertion rod with a coupon adapter, and a packing gland. A safety chain and safety nut are also provided to prevent blowout. Standard packing material in the packing gland is Teflon®, however, grafoil packing can be provided for high temperature applications. Several coupon holders and lengths are available. *The insertion length (I.L.) shown here is based on a standard Metal Samples Corrosion Monitoring Systems part #CO118 coupon and may vary for other coupons depending on the coupon length and hole location.
