It’s a dual-hardness, non-sparking rubber funnel for highly reactive materials
The client was mixing volatile materials and needed a funnel that would hold its shape, but would also not cause any kind of friction with the materials. In other words, it needed to be hard on the outside and soft on the inside. Field Rubber designed a disposable funnel that was built with Shore Durometer 70D rubber on the outside dimension and Shore Durometer 40A rubber on the inside.
