AS/NZS 4020
AS/NZS 4020 is the joint Australian/New Zealand standard that defines how materials are tested for use in contact with drinking water. It ensures products will not change taste, odour or appearance, will not leach harmful substances, and will not support microbial growth. For anyone working with potable water infrastructure, this approval is the recognised benchmark.
SHUK carries a focused range of gasket materials that meet this important standard. These materials are chosen for their sealing performance, reliability under pressure, and proven compliance in water applications. With TESNIT® BA-50 held exclusively by SHUK in New Zealand, alongside KLINGERSIL® C-4430 and potable-grade EPDM rubber, we can support potable water projects across municipal, industrial, and commercial sectors.
Our approach is to stock products that give contractors, engineers and asset managers the assurance of compliance without compromise. These materials are specified across:
-
Municipal and rural water reticulation
-
Treatment plants and pump stations
-
Potable water valves, meters, and backflow assemblies
-
Food and beverage facilities using mains water
If the job involves potable water and requires confidence in sealing and compliance, SHUK’s AS/NZS 4020-approved range provides a straightforward solution.
