Is the SMS SZK Stainless Steel End with GZ Notched Tail compatible with food-grade gaskets for operation up to 10 bar per BS 4825-5?

Yes. The SMS SZK Stainless Steel End with GZ Notched Tail is compatible with food‑grade gaskets for operation up to 10 bar per BS 4825‑5. Its internal surface roughness of Ra 0.8 µm meets hygienic requirements for food and beverage use, and the AISI 316 stainless steel construction provides corrosion resistance and durability. The connection is rated to withstand a maximum working pressure of 10 bar according to BS 4825‑5; the allowable operating temperature will depend on the specific food‑grade gasket material selected.

Can the SMS SZK Stainless Steel End with GZ Notched Tail be used with high-temperature gaskets for processes exceeding standard temperature ranges?

Yes — the SMS SZK Stainless Steel End with GZ Notched Tail can be used with high-temperature gaskets for processes that exceed standard temperature ranges, provided the gasket material you select is rated for those temperatures. The fitting itself is made from AISI 316 stainless steel and designed for hygienic, high-performance use (Ra 0.8 µm inside bore, up to 10 bar per BS 4825-5), but its allowable operating temperature is governed by the gasket compound. Choose a gasket specifically specified for the required maximum temperature (and chemical compatibility) to ensure sealing integrity and long-term performance.
