Smc Pneumatics KQ2E01-35A Female Bulkhead Tube Fitting

Product Description

The SMC PNEUMATICS KQ2E01-35A is a push-to-connect female bulkhead tube fitting designed for quick, tool-free pneumatic tubing connections through panel walls and enclosures. Constructed from brass with a polybutylene tube collet, this fitting accepts 1/8 inch OD tubing and connects via a 1/4 inch NPT female thread. It is rated for a maximum working pressure of 145 psi, making it well-suited for standard compressed air and pneumatic control circuits. Licensed pneumatic system technicians, automation integrators, and industrial maintenance professionals install this fitting where a secure, leak-free tube pass-through is required in a bulkhead or panel application.

This fitting is used in pneumatic plumbing systems where tubing must pass through a panel, manifold, or enclosure wall. Typical applications include compressed air distribution, pneumatic control systems, and light industrial automation. The NPT thread provides compatibility with standard North American pipe fittings and ports. It operates within a temperature range of 23 degrees F to 140 degrees F, suitable for indoor industrial and light commercial environments. The RoHS-compliant construction supports use in electronics-adjacent assemblies where restricted substance compliance is required.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure hold
• Female bulkhead configuration for panel or enclosure pass-through installations
• Rated to 145 psi maximum working pressure for standard pneumatic circuits
• 1/4 inch NPT female thread for compatibility with standard North American pipe ports
• Brass body with polybutylene collet for durability and chemical resistance
• RoHS compliant for use in restricted-substance environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for pneumatic tubing systems using 1/8 inch OD tubing with 1/4 inch NPT ported equipment.

Installation Notes

Installation is typically performed by pneumatic system technicians or industrial maintenance professionals. Depressurize the system completely before removing or installing any fittings. Apply thread sealant tape to NPT threads in accordance with applicable pneumatic plumbing standards before making the threaded connection. Do not exceed the rated working pressure of 145 psi or the maximum temperature limit of 140 degrees F during operation.
