Infinity Tools 4" Splice

It fits between two sections of 4" hose to join them into one continuous run, letting you extend your dust collection line. See more dust collection fittings.

It is designed for 4" hose, joining two 4" sections together.

When one length of hose will not reach a machine, a splice connects two sections so you can extend the run as far as the layout requires.

It is intended to join two sections of 4" hose. If you cut out a damaged area, the splice can reconnect the two remaining sections into a continuous run.

Keeping runs short and direct preserves airflow, but when extra length is necessary, splicing two sections is a clean way to extend the line. Pair it with quality dust collection hoses.

It is part of the Infinity Cutting Tools dust collection lineup. Browse the full dust collection collection.

You can add a splice wherever two hose sections meet. Use as many as your layout requires, keeping the overall run as direct as possible for the best airflow.

Yes. The splice simply fits between two sections of 4" hose, so you slide each hose end onto the coupler to make the connection.

Clamps are not included, but securing each hose end to the splice helps keep the joint tight and airtight over time.
