3-A Sanitary standards require the hose end fitting to be sealed against the ingress of external fluid into the fitting construction. Aflex Hose have implemented a silicone seal between the ferrule and fi tting to address this requirement. The direct crimp style fitting does not incorporate the silicone seal as standard and a modified version of the fitting for 3-A is required.
When ordering customers should specify that the hose assembly must meet 3-A sanitary requirements. The 3-A symbol and appropriate marking to 3-A requirements will be applied to the hose assembly.
Bioflex Ultra covered hoses are soakable in both standard and 3-A sanitary configurations. The 3-A assembly is only available with an EPDM or silicone cover.
The Aflex Hose 3-A certificate is available to view on our website in the 'certifications' section. The Aflex Hose 3-A certificate is also available to view on the 3-A Sanitary website . Follow the link to the database search page and search for “Aflex Hose” under view company listings.
