PortMatch guides
Practical guides to measuring, sizing and choosing the right part, from the same sourced data behind the fitment tool.
Dust port and hose size standards for workshopsThe common dust extraction sizes, from 2.5 inch and 4 inch shop-vac and collector fittings to the 27, 35 and 50 millimetre metric tool ports.Imperial versus metric dust ports: 4 inch and 100 mmWhy 4 inch and 100 mm, or 2.5 inch and 63 mm, are close but not equal, and how the small difference affects a push fit.Tool-port to hose adapters for dust extractionHow adapters bridge a tool's dust port to a vacuum or collector hose, and how to pick one that seals on both ends.How to match a dust extractor to a toolWhy airflow and suction, not just hose size, decide whether an extractor clears a tool's dust, and how to pair the two.How to measure a dust portMeasure a tool's dust port correctly, tell inner from outer diameter, and read whether it is imperial or metric so you can match a hose.Reducing and stepping fittings for dust extractionHow reducers step a duct from one diameter to another, why every reduction costs airflow, and how to keep losses down.Anti-static dust extraction hose explainedWhy dry dust moving through a hose builds static, what anti-static hose does about it, and when it matters.
