Product catalog summary

Overview: The document introduces the KQ2 series of one-touch fittings, which consolidate previous models into a single enhanced version. These fittings are lightweight, compact, and offer improved variations for various applications.

Specifications: The KQ2 series includes 51 models with three seal methods: gasket seal, sealant, and face seal. They support both metric and inch sizes for tubing outer diameters and are suitable for nylon and urethane tubing.

Design Improvements: The KQ2 fittings feature a 30% reduction in insertion force and a 20% reduction in removal force compared to existing models. They are 24% smaller in height and 23% smaller in horizontal dimensions.

Material and Treatment Options: Available in brass with or without electroless nickel plating, and stainless steel options for certain components.

Seal Methods: Face seals prevent residue and allow for multiple re-piping without degradation, offering advantages over traditional sealants.

Connection Threads: Supports Rc, G, NPT, and NPTF threads, making it versatile for different piping requirements.

Installation and Usage: Designed for easy installation with reduced tool-tightening requirements. Suitable for confined spaces due to compact design and rotating body parts.

Applications: Applicable for pressures from low vacuum to 1 MPa, suitable for various industrial settings.

Ordering Information: Detailed instructions on ordering, including variations, dimensions, and made-to-order options, along with spare parts and accessories.

Key Features: Face seal design ensures a secure and leak-proof connection. Available in various configurations like elbows, tees, and unions.

Usage and Limitations: Not guaranteed for zero leakage; should not be used with a leak tester or for vacuum retention. Surge pressure must remain under maximum operating pressure.

Installation Procedures: Includes preparation, sealant tape application, model and size verification, and proper tool usage to avoid damage.

Design and Selection Warnings: Products are designed for compressed air systems only. Avoid disassembly or modifications to prevent accidents.

Operating Environment: Consult SMC for non-compressed air applications. Use antistatic or flame-resistant fittings in problematic environments.

Maintenance: Regular inspection and replacement of damaged fittings or tubing are recommended. Ensure safety measures during maintenance.

Connection Thread Tightening: Follow specified torque values for different thread sizes to prevent damage or leakage.

Safety and Compliance: Product compatibility is the responsibility of the equipment designer. Only trained personnel should operate machinery, and safety measures must be confirmed before servicing.

Warranty and Disclaimer: The product warranty is 1 year in service or 1.5 years after delivery, covering manufacturing defects but excluding consumable parts.
