1 inch x 20 foot vacuum and air hose assembly combines dust collection and air supply in a single run, which helps streamline tool hookups on woodworking and other shop equipment. The hose is identified as a 19.7 inch conductive vacuum hose with an integrated 5/16 inch air line, so dust and air lines stay together along the working length for easier routing around benches and machinery. The conductive vacuum hose design supports grounding within a dust collection system layout, which matters in environments where fine dust is regularly moved. The integrated 5/16 inch air line is built directly into the hose assembly, so the air supply follows the vacuum line path and stays close to the connected tool. This assembly is part of the Dynabrade line, tying directly to their MINI RAPTOR VAC applications where combined air and vacuum service improves day-to-day workflow.
The conductive vacuum hose with integrated 5/16 inch air line is configured as a combined pathway, so both vacuum and air connections are managed in one hose route during installation around benches or tools. The 1 inch diameter on the vacuum side sets the hose size that will interface with dust collection fittings or cuffs sized to this dimension, which helps plan transitions to other duct or hose sections. The 5/16 inch air line dimension describes the internal air passage sized for pneumatic tools that operate on this hose ID, keeping air supply consistent along the length. The presence of one 1/4 inch NPT coupler and two 1/4 inch NPT connectors defines the available threaded points, which guides how the air line ties into upstream supply and downstream tool-side connections in an installed system.
This MINI RAPTOR VAC hose assembly sits in the dust collectors and accessories class, so it is intended for dust collection roles around woodworking tools and similar shop equipment where airborne debris must be drawn away from the work. The 1 inch diameter vacuum hose dimension aligns with dust collection branches that are sized for this smaller hose, which is typical near handheld or small-station tools. The conductive vacuum hose characteristic fits dust collection layouts that use conductive hose segments as part of an overall system design. The integrated 5/16 inch air line supports pneumatic tools that share the same route as the dust hose, so the same assembly can serve both suction and air delivery at the tool location. With the Dynabrade brand and MINI RAPTOR VAC description, this assembly fits into setups that utilize Dynabrade tools and dust collection strategies built around their equipment line.
The combination of a 1 inch diameter vacuum hose and a 19.7 inch conductive length gives a defined hose segment for planning tool reach, which matters when positioning dust collection in relation to benches or sanding stations. The conductive vacuum hose attribute affects how the hose behaves when moving dust-laden air, which supports system behavior that accounts for conductive paths. The integrated 5/16 inch air line keeps the pneumatic hose permanently aligned with the vacuum hose, so repositioning the assembly moves both air and dust connections together, reducing hose tangling around the work area. The specified 1/4 inch NPT coupler and two 1/4 inch NPT connectors mean the air line offers multiple threaded points, which can help maintain consistent air routing when integrating this assembly between existing air drops and the connected pneumatic tool. Being identified with manufacturer part number 31972 provides an exact reference when repeating the same assembly across multiple stations.
The Dynabrade 31972 hose assembly is a 1 inch x 20 foot vacuum and air hose assembly with a conductive vacuum hose and an integrated 5/16 inch air line for combined dust and air service.
The hose assembly uses a 19.7 inch conductive vacuum hose length, giving a defined reach segment that can be factored into dust collection layouts around tools or benches.
The vacuum hose has a 1 inch diameter, which sets the hose size for matching to 1 inch dust collection fittings or small-tool hose connections in a system.
The integrated air line is 5/16 inch, so pneumatic tools designed around a 5/16 inch air line can be supplied through this combined vacuum and air hose assembly.
The air line portion uses one 1/4 inch NPT coupler and two 1/4 inch NPT connectors, giving several 1/4 inch NPT threaded points for integrating into air system plumbing.
The conductive vacuum hose design provides a conductive path through the hose segment, which fits dust collection layouts that rely on conductive sections within the hose run.
This MINI RAPTOR VAC hose assembly from Dynabrade brings together a 1 inch diameter conductive vacuum hose and a 5/16 inch integrated air line, so one component serves both suction and air service at the tool. The 19.7 inch conductive hose length, paired with one 1/4 inch NPT coupler and two 1/4 inch NPT connectors, defines a clear segment for building out repeatable stations across a shop. For setups using Dynabrade dust collection accessories in the dust collectors and accessories class, this 31972 hose assembly offers a defined way to route dust collection and air supply to the same working location.
