A complete coupling consists of coupling housing, nuts, bolts, and gasket. The coupling housing contains and compresses the gasket, which affects proper sealing of the joint. Piedmont gaskets are designed for a tight seal in high pressure industrial applications.
Features & Benefits
C-Shaped Gaskets
The C-shaped gasket is recommended to be used in situations where the temperature will range from -30° F to 230° F (-34° C to 110° C). Suitable for hot or cold water, seawater and brine water, diluite acids, oil free and many chemical services, the C-shaped gasket is also appropriate for potable water service.
Made of ethylene propylene diene monomer (EPDM) rubber the C-shaped gasket has an excellent resistance to oxidation while being highly durable against heat. The C-shaped gasket is available in different materials.
The C-shaped gasket meets the following certifications NSF approved, ANSI 91.
Flush-Fit Gasket
The Flush-fit gasket is recommended for vacuum services. The inner lip minimizes turbulence in high-velocity applications. This gasket is to be used in situations where the temperature will range from -30° F to 230° F (-34° C to 110° C). Suitable for hot or cold water, seawater and brine water, diluite acids, oil free and many chemical services, the Flush-fit gasket is also appropriate for potable water service.

The Flush-Fit gasket meets the following certifications NSF approved, ANSI 91.
Bolts
Bolts are used to hold the two housing parts of the coupling together. Made of stainless steel 316 with a round head and square neck, the bolts are corrosion free. If stainless steel nuts are used with stainless steel bolts, commercial anti-seize compound should be applied to the bolt threads.
Nuts
Nuts are used to tighten the two housing parts of the coupling together. Made of stainless steel 316, the hexagonal heavy nut style used is corrosion free. If stainless steel nuts are used with stainless steel bolts, commercial anti-seize compound should be applied to the bolt threads.
