Smc Pneumatics KQ2R08-10A Plug-in Reducer Fitting 8mm X 10mm

Product Description

The SMC PNEUMATICS KQ2R08-10A is a push-to-connect plug-in reducer tube fitting designed to join two pneumatic or fluid lines of different outer diameters without tools. The fitting accepts an 8mm outer diameter tube on one end and a 10mm outer diameter stem on the other, allowing a quick inline reduction in a single compact component. Built from brass with polybutylene construction, it is rated to 145 psi maximum working pressure and operates across a temperature range of 23 degrees F to 140 degrees F. HVAC technicians, pneumatic system installers, and industrial plumbing professionals use this fitting in compressed air, vacuum, and compatible fluid line assemblies where a fast, leak-resistant connection is required.

The KQ2R08-10A is suited for light commercial and industrial pneumatic tubing runs where a reduction between an 8mm and 10mm tube outside diameter is needed inline. Its push-to-connect design speeds up installation in tight panel spaces, manifold assemblies, and equipment enclosures. The overall length of the fitting is approximately 1.38 inches (35.10mm), making it compact enough for installations with limited clearance. This fitting is RoHS compliant, making it appropriate for applications with environmental material restrictions.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Reduces from 10mm stem outside diameter to 8mm tube outside diameter in a single inline fitting
• Brass and polybutylene construction for durability in pneumatic service
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant materials

Compatibility

Designed as an OEM-style push-to-connect reducer fitting for pneumatic tubing systems using 8mm and 10mm outside diameter flexible tube, consistent with standard compressed air and vacuum line assemblies.

Installation Notes

Installation is performed by trained pneumatic or HVAC technicians. Depressurize and lock out the air supply before servicing any pneumatic line. Ensure tube ends are cut cleanly and squarely with a proper tube cutter before insertion to maintain a leak-free seal. Verify the connected tube outer diameters match the fitting specifications before use.
