Filters with character: Blue.on Heavy Duty

Our answer to environmental pollution caused by spin-on filters is the sustainable filtration concept Blue.on. This concept consists of three components: A plastic lid, a Filter Elements and the valve adapter.

Spin.off - Blue.on

The Blue.on HD filter from Hengst is our characterful answer to the conventional spin-on filter. The patented technology is particularly easy to install and replace. Thanks to patent protection, our Blue.on filter also guarantees you maximum aftermarket sales, including plagiarism protection. And Blue.on also performs fantastically when it comes to sustainability: both the valve adapter and the filter housing are lifetime components. The Filter Elements are also the only service part that is 100% recyclable. All in all, this means 90% less waste, 25% less weight and significantly more service parts business for you.
