Hydrotite Blue EPDM Gasket

In November 2016, Allied Fastenings Limited was formally notified the Blue EPDM Gasket compliant with AS/NZS4020 had been accepted by Watercare and will be specified in their Material Supply Standard document. Since November other water authorities have been approached including HCC, CCC, Wellington Water, Carterton DC, HDC, Manawatu and Wanganui DC’s, all whom have approved the use of the Blue EPDM gasket. The process of ongoing meetings with major NZ water authorities is currently in process.

Following three years of product development and testing, this is a significant step forward by respective water authorities to ensure the AS/NZS4020 Standard for potable water is adhered by suppliers and contractors. It has been clearly articulated, authorities intend to strictly police this standard now that a viable elastomeric gasket option for potable water is available.

It should be noted the Allied Fastenings Blue EPDM Gasket is the only reinforced elastomeric Blue EPDM gasket which meets AS/NZS4020 approved by the Australian Water Standards Authority suitable for the potable water market in NZ. This approved formulation is supplied exclusively through Hygrade, a member of the Hynds Group of companies.

Further to this advice it should be noted Watercare also stipulate Molybond anti-seize to be used on Stainless Steel bolting assemblies. Allied Fastenings distribute genuine Molybond coated stainless components also through the Hygrade networks.

In keeping with company practice Allied Fastenings will only supply to ISO or nationally recognised Standards – this practice will not be compromised.
