Flexible Connection Hose Beulco 6030 Diffuflex (Dimensions: 15 mm / 22 mm / 28 mm)

Prevent oxygen ingress and safeguard your heating or cooling system against internal corrosion with the Beulco 6030 Diffuflex. 

This premium, oxygen-diffusion-tight connection hose is a professional-grade solution engineered specifically for fixed installations inside sealed circuit networks. By effectively blocking oxygen from migrating into the system fluid, it dramatically reduces the risk of rust accumulation, clogged valves, and unexpected operational breakdowns, securing maximum long-term thermal efficiency.

Premium butyl rubber core and heavy-duty steel braiding
The defining performance benchmark of this series lies within its select choice of raw materials. The internal core hose is manufactured from a high-performance butyl rubber compound that is rigorously audited against international benchmarks. Testing confirms that Diffuflex exhibits a staggering 20 times lower oxygen permeability rating than conventional EPDM rubber hoses. To withstand elevated system pressures and guarantee extreme mechanical durability, the line is shielded by a tight, industrial-grade stainless steel wire braiding complete with an interwoven black marker strand.

Adaptive sizing layout and clean smooth-pipe ends
The model 6030 architecture features a streamlined design completed with straight, smooth pipe ends (spigot connections) on both sides, making it exceptionally well-suited for fast and dependable pairing with standard compression fittings or press-sleeve configurations. To facilitate all types of unique mechanical manifests, the hose is supplied across three pipe outside diameters (15 mm, 22 mm, and 28 mm) alongside multiple standard lengths spanning from 400 mm up to 1000 mm. The line is certified to channel media such as heating loop water, chilled water, and glycol-antifreeze compounds.
