Is the End piece with GZ BSP and anti-bending spring, stainless steel, type AK suitable for washing hoses operating at up to 40 bar?

Yes. End piece with GZ BSP and anti-bending spring, stainless steel, type AK is suitable for washing hoses operating at up to 40 bar. It is designed for installation in industrial hoses, specifically for washing-hose connections at the water-gun interface where repeated bending occurs. The included anti-kink spring protects the hose at the critical flex point, and the AISI 316 stainless steel construction ensures corrosion resistance and durability. The specified working pressure is up to 40 bar, matching the operating condition you stated.

Can the End piece with GZ BSP and anti-bending spring, stainless steel, type AK be fitted to existing hose assemblies without special tools?

Yes. The End piece with GZ BSP and anti-bending spring, stainless steel, type AK is designed for installation in industrial hoses (notably washing hoses at the water-gun connection) and can be fitted to existing hose assemblies without special tools, provided the hose end matches the external GZ BSP thread and appropriate inner diameter for the 200 mm anti-kink spring. Ensure correct thread size and pressure rating (up to 40 bar) are compatible with the hose and application; use proper sealing (PTFE tape or sealant) as needed.

Does the End piece with GZ BSP and anti-bending spring, stainless steel, type AK resist corrosion in saltwater environments?

Yes. The End piece with GZ BSP and anti-bending spring, stainless steel, type AK is made from AISI 316 stainless steel, which offers excellent corrosion resistance in chloride-rich environments such as saltwater. AISI 316 contains molybdenum, which significantly improves resistance to pitting and crevice corrosion compared with AISI 304, making it suitable for marine and coastal applications. With proper maintenance and avoidance of prolonged deposits or aggressive chemical exposure, the component should resist corrosion in saltwater environments while operating up to its specified working pressure of 40 bar.
