Bonfix – Bend 90° Stainless Steel 316L 28 mm Press KIWA

Sized at 28 mm with a full 90° change of direction, this Bonfix press bend is the go-to elbow for pool plant rooms and heat-pump pipework where stainless steel is specified. The KIWA/DVGW dual approval confirms suitability for drinking-water and heating installations across the Netherlands, Germany, and beyond — essential assurance for professional installers working to local codes. The 316L grade material offers superior resistance to chlorinated water and corrosive pool-chemical environments compared with standard 304 stainless.

The press-fit system joins pipe without any welding, soldering, or open flame on site. A standard M-profile pressing tool crimps the fitting onto the pipe in seconds, with an O-ring seated inside the socket ensuring a leak-proof seal. This makes the fitting well suited to confined pool-plant enclosures where hot-working is impractical or prohibited.

Material & corrosion resistance

Grade 316L stainless steel contains molybdenum, which gives it markedly better resistance to chloride pitting and crevice corrosion than 304 — a significant advantage in pool and spa environments where water chemistry and salt systems can accelerate corrosion. The low-carbon ‘L’ designation also minimises sensitisation risk at weld zones in adjacent pipework.

Approvals & system compatibility

KIWA and DVGW certification means this fitting meets rigorous Dutch and German standards for potable water and heating circuits, satisfying compliance requirements for both residential pools with heat pumps and commercial spa installations. As part of the Bonfix Press-Inox system, it integrates directly with the wider range of 28 mm press fittings — T-pieces, couplings, reducers, and adaptor elbows — for a fully consistent, single-system installation.
