How to order
Confirm (a) end-connection size and style on each side, (b) operating pressure / temperature envelope, (c) any required certifications, (d) seal material preference (NBR / FKM / FFKM / PEEK / Teflon — drives chemical compatibility and temperature limit). Indus matches the coupling halves to your hose assemblies and supplies the matched gaskets and fasteners.
Companion products
Order in matched pairs (male and female halves) for new installations, or as service spares for existing assemblies. Indus also supplies matched seal kits for routine maintenance, plus replacement gaskets and fasteners.
