IS 5382 specifies rubber sealing rings used in pipe joints for water, gas, and sewer applications. EPDM rubber is the standard material for water supply. The rings provide a flexible, watertight seal at push-fit (Tyton) joints in DI, concrete, and plastic pipes.
Specification for rubber sealing rings (gaskets) for use in joints of pipes for gas, water supply, and sewerage, covering material, dimensions, and testing.

Practical Notes
! EPDM is the preferred material for potable water applications — SBR is NOT suitable for drinking water.
! Store rings away from direct sunlight and ozone sources (electric motors) — rubber degrades under UV/ozone.
! Always clean the pipe spigot and socket before inserting the ring — dirt causes leakage.
! Lubricate with approved joint lubricant only — never use grease, oil, or soap which degrades rubber.
