Shield SDG-27 is a high pressure flexible coupling can be used in different applications where high pressure service is required.
Standard - SDG-25
Shield Flexible Couplings allow controlled angular movement of the pipe to assist alignment and installation. The advantage of flexibility must be considered in the design for hanger and support Spacing.
Light - SDG-21
SDG-21 is designed for a maximum working pressure of 300psi. The flexibility benefits of this coupling can be used in applications where high pressure is not required.
