KQ2Y Series Male Run Tee Push-in Fitting

SOLH KQ2Y Series Male Run Tee Push-in Fitting | Service Tee Pneumatic Connector

Brand: SOLH by Richge Technology | SMC KQ2Y Equivalent Male Run Tee (Service Tee) One-Touch Fitting

1. Product Overview

     KQ2Y is the Male Run Tee (commonly known as Service Tee) of SOLH KQ2 one-touch fitting series. Its core configuration is 1 male thread inlet + 2 equal-diameter push-in outlets. It branches two air tubes directly from the main threaded port and is one of the most widely used branch fittings in pneumatic systems.

2. Model Naming Rules

  Model breakdown example:KQ2Y06-01AS
     KQ2: KQ2 series second-generation push-in fitting (white body)
     Y: Run Tee, male thread T-type tee (1 threaded inlet, 2 push-in outlets)
     06: Outer diameter of tubing for push-in outlets: φ6mm
     01: Male thread specification (R18; metric M3/M5/M6)
     A: Gasket seal for repeated assembly & disassembly; S: Pre-applied thread sealant, non-reusable; N: Nickel-plated corrosion resistant

  Example: KQ2Y04-M5A → M5 male thread inlet, dual φ4mm push-in outlets, gasket seal.

3. Structure & Core Features

  3.1 T-Type Structure (1 In, 2 Out)

     • Inlet: Male thread (Metric M / Imperial R), connects to valves, air cylinders and main pipelines

     • Outlets: 2 equal-diameter push-in ports for PU / nylon tubing, tool-free connection

     • Thread end supports 360° rotation. Orientation can be freely adjusted after mounting to eliminate twisting stress on tubing.

  3.2 Key Advantages

     • Service-friendly design: No need to cut the main tubing. Branch directly from threaded port for easy circuit addition and maintenance.

     • Compact & lightweight: PBT plastic body + nickel-plated brass thread, small footprint and low weight.

     • Vacuum compatible: Works from -100kPa vacuum up to 1.0MPa positive pressure, suitable for vacuum circuits.

     • High sealing performance: NBR sealing ring. Type A gasket allows repeated disassembly; Type S pre-coated sealant prevents leakage.

     • Easy tube release: Round release button. Press to remove tubing without damaging tube outer wall.

6. Selection Comparison: KQ2Y vs KQ2D vs KQ2T

7. Selection & Installation Guidelines

  Selection Guide

     • Branch from solenoid valve / cylinder male thread port → KQ2Y (e.g. KQ2Y06-01AS)

     • 1-to-2 split in mid-tubing, low noise requirement → KQ2D

     • Standard right-angle split, cost-sensitive project → KQ2T

  Installation Notes

     • Cut tubing flat without burrs. Insert tubing fully until you hear a click to avoid air leakage.

     • Type A (gasket) can be repeatedly disassembled; Type S (pre-coated sealant) needs re-sealing after disassembly.

     • For vacuum applications, select Type A with NBR seal to maintain stable vacuum level.

8. Typical Applications

     • Solenoid valve outlet branching: KQ2Y06-01AS fitted on R1/8 port of 5/2-way solenoid valve to supply two air cylinders.

     • Synchronized cylinder control: KQ2Y08-02AS on main R1/4 threaded port to split into two φ8 tubes for dual cylinder synchronous actuation.

     • Vacuum circuit retrofit: Branch from vacuum generator main thread port to vacuum suction cups, easy for maintenance and modification.
