Smc Pneumatics KQ2W04-01AS Extended Male Elbow Fitting

Product Description

The SMC PNEUMATICS KQ2W04-01AS is a push-to-connect extended male elbow tube fitting designed for pneumatic plumbing applications. It accepts 4mm outside-diameter tubing and connects via a BSPT 1/8-inch male thread. The body is constructed from brass with a polybutylene internal sleeve, rated for a maximum working pressure of 145 psi. The extended elbow configuration provides clearance in tight panel or manifold installations where a standard elbow would foul adjacent components. This fitting is installed by pneumatic technicians and industrial maintenance professionals working on compressed-air systems.

The KQ2W04-01AS is suited for use in light industrial and OEM pneumatic circuit assemblies where 4mm tubing is routed at a 90-degree change of direction. Its push-to-connect design allows tool-free tube insertion and removal, reducing assembly time on production equipment, pneumatic actuator circuits, and air-preparation component manifolds. The BSPT thread makes it appropriate for equipment built to metric or ISO pneumatic plumbing standards.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Extended elbow body provides clearance in congested panel or manifold layouts
• Brass construction with polybutylene sleeve for durability in compressed-air service
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant materials

Compatibility

Designed for use with 4mm outside-diameter polyurethane, nylon, or compatible push-to-connect pneumatic tubing in systems with BSPT-threaded ports.

Installation Notes

Installation is performed by pneumatic technicians or qualified industrial maintenance personnel. Depressurize and lock out the compressed-air circuit before removing or installing any fittings. Verify the mating port thread standard is BSPT before installation, as BSPT and NPT threads are not interchangeable. Ensure tubing is cut square and deburred before inserting into the fitting to maintain a proper seal.
