The Slurryflex SM-Series Muff Coupling Mining Hose is a straight length hard-wall hose with an integral flange on one end, and a split-body muff coupling on the other.

This type of hose is used when the distance from pipe to pipe can’t be accurately measured. The SM-Series mining hose can be cut to length on site and retrofitted into the pipework with the muff coupling. The hose’s pressure rating is based on the pressure rating of the muff coupling.

Slurryflex Grade A rubber gives you long-term resistance to abrasion, cutting, and tearing. Independent tests have shown that Slurryflex hoses are the most flexible, longest lasting slurry hoses on the market.

All of our mining hoses are custom made in Australia to your specifications. We have the largest mining hose factory in Australia and use a hot vulcanisation process to produce a robust, premium hose. Talk to us about your requirements and we’ll help you choose the right hose for the job.
