KQ2N Series Straight Push-in Fitting

KQ2N stem-style straight push-in fittings are one-touch pneumatic connectors engineered as drop-in replacements for SMC KQ2N series. Featuring male thread, equal-diameter stem and reducing stem variants, these fittings support quick tool-free tube assembly for PU and PA tubing. Suitable for both compressed air and vacuum pipelines in automation equipment, robotic handling and pneumatic fixture applications. PBT body paired with nickel-plated brass threads delivers stable sealing within 0℃~60℃ working temperature.

SOLH KQ2N Series Straight Push-in Fitting | Stem Type Pneumatic Straight Connector

Brand: SOLH by Richge Technology | SMC KQ2N Equivalent Stem Straight One-Touch Fitting








1. Product Overview

   KQ2N is a stem-style straight pneumatic fitting. One end is male thread or stem, the other end accepts PU/PA air tubing. It is a direct replacement for SMC KQ2N series one-touch fittings. Widely used in pneumatic circuits and vacuum pipelines. Tool-free installation, simply press the release collar to insert or remove tubing quickly.

   Four structural types available:

      Male thread stem type (M thread: M5)

      Male thread stem type (Imperial taper R thread: 1/8,1/4,3/8)

     • Equal diameter stem straight (-99 suffix): both ends with same OD stem

     • Reducing stem straight fitting: two stems with different outer diameters for size transition


2. Model Code Explanation

  Example: KQ2N04-M5

     • KQ2N: Series code, stem type straight fitting

     • 04: Tube outer diameter Φ4mm on push-in side

     • M5 / 01S / 02S: Male thread specification

     • -99: Equal diameter stem straight fitting

     • 04-06: Reducing stem fitting, ①Φ4 → ②Φ6
