Smc Pneumatics KQ2L10-99A Push-to-connect Plug 145 Psi

Product Description

The SMC PNEUMATICS KQ2L10-99A is a push-to-connect tube fitting plug designed to seal off open pneumatic or fluid lines quickly and without tools. Constructed from brass with a polybutylene tube interface, it accepts 10mm outside diameter tubing and holds a maximum working pressure of 145 psi. This fitting is a common component in compressed air distribution systems, pneumatic control circuits, and low-pressure fluid lines where a port or line end needs to be capped during maintenance or system reconfiguration. Licensed trades and industrial maintenance technicians routinely stock this style of plug for fast line isolation.

This plug fitting is suited for use in residential, commercial, and light industrial pneumatic systems. It is appropriate for compressed air lines, pneumatic control panels, and similar low-pressure tubing networks where a 10mm OD tube connection must be terminated. The push-to-connect design allows the fitting to be installed and removed without pipe wrenches or thread sealant, making it practical for retrofit and service work where quick line isolation is needed.

Key Features

• Push-to-connect design accepts 10mm outside diameter tubing with no tools required
• Brass construction provides corrosion resistance and durability in pneumatic service
• Rated to 145 psi maximum working pressure
• Operating temperature range from 23 degrees F to 140 degrees F
• RoHS compliant materials
• Compact plug form factor seals open line ends or unused ports during service

Compatibility

Designed as an OEM-style push-to-connect plug for pneumatic and low-pressure fluid tubing systems using 10mm outside diameter tubing.

Installation Notes

This fitting is typically installed by licensed pipefitters, pneumatic system technicians, or industrial maintenance mechanics. Always depressurize and lock out the air supply before inserting or removing push-to-connect fittings. Verify that the tubing outside diameter matches the 10mm fitting specification and that the tube end is cut cleanly and squarely before insertion. Do not exceed the 145 psi maximum working pressure rating or operate outside the listed temperature range.
