KM3N8-500 Quick Coupling

Product Introduction

KM3N8-500 is a male quick coupling designed for efficient connection and disconnection in fluid handling systems. Made from POM, this white quick coupling combines practical installation, reliable connection performance, and cost-effective material selection for applications requiring convenient tubing or piping connections.

The coupling belongs to the B0 series and features a 3/8-18NPT threaded end. Its male configuration provides a practical connection solution for compatible female components, while the compact coupling structure supports easy system assembly and maintenance.

Aiiboom Technology provides configurable quick coupling solutions with different series, materials, thread standards, valve options, mounting configurations, colors, and sealing materials to accommodate different system requirements.

Key Product Features

1. High Precision

KM3N8-500 is designed with a precision connection structure to support consistent mating between compatible components and reliable fluid system assembly.

2. Convenient Connection

The quick coupling design allows components to be connected and disconnected efficiently, helping simplify installation, replacement, inspection, and maintenance operations.

3. Cost-Effective POM Construction

The coupling is manufactured from POM, providing a practical material solution for applications where lightweight construction, dimensional stability, and cost efficiency are important.

4. Reliable Connection

The male threaded configuration provides a secure connection with compatible components. The 3/8-18NPT thread is suitable for systems designed around the corresponding NPT connection standard.

5. Configurable Product Platform

The KM series supports multiple options for series, mounting, material, color, thread, valve, and O-ring selection, allowing buyers to configure coupling solutions according to application requirements.

Performance Parameters

Application Advantages

The KM3N8-500 Quick Coupling is suitable for fluid handling systems where convenient component connection and disconnection are required. It can be considered for equipment, tubing assemblies, fluid transfer systems, pneumatic or liquid handling arrangements, and other compatible industrial connection applications.

Its threaded male end allows integration with matching components, while the quick coupling structure supports easier system maintenance compared with permanently fixed connections.

Before selection, users should confirm the required thread specification, working medium, temperature, pressure, sealing material, and compatibility of all mating components.

Product Selection & Configuration

The KM series provides multiple configuration codes that allow buyers to specify the coupling according to connection and application requirements.

End Configuration

• M: Male

• F: Female

Shut-Off Valve

• C: With shut-off

• No C: Without shut-off

KM3N8-500 is configured as a male coupling without a shut-off valve.

Body Configuration

• L: 90° elbow

• No L: Straight

Thread Options

Available threaded-end codes include:

• 1U4: 1/4-28 UNF

• 1N8: 1/8-27 NPT

• 1B8: 1/8-28 BSPT

The KM3N8-500 specification uses a 3/8-18NPT threaded connection.

Material Options

The coupling platform supports multiple primary material choices:

• 0: POM

• 1: SUS316

• 5: PEEK

• 6: PP

The standard KM3N8-500 configuration uses POM.

Material selection should be based on the working medium, temperature, pressure, chemical compatibility, mechanical requirements, and operating environment.

Color Options

Available color codes include:

• N: Natural

• B: Black

• W: White

• O: Orange

• R: Red

• G: Green

• U: Blue

• H: Gray

• Y: Yellow

KM3N8-500 is supplied in white under its specified configuration. Custom color requirements can be evaluated for suitable orders.

O-Ring Options

Different O-ring materials can be selected according to application conditions:

• EPDM: Default option

• FFKM: For applications requiring higher chemical and temperature resistance

• FKM: For suitable chemical and temperature conditions

• NBR: For compatible general industrial applications

The appropriate sealing material should be selected according to the fluid medium, temperature range, pressure, and compatibility requirements of the system.

Panel Mount Options

The product selection platform also supports different panel mounting configurations:

• 0: No panel mount

• 1: No nut

• 2: Panel mount + 304 nut

• 4: Panel mount + POM nut

• 5: Panel mount + PP nut

Panel-mount configurations can be selected when the coupling needs to be installed through a system panel or equipment housing.

Panel Mount O-Ring Options

Panel mounting configurations can be matched with different sealing materials:

• N: NBR

• E: EPDM

• M: Other custom material

The final configuration should be confirmed according to the installation structure and sealing requirements.

Product Code Selection Guide

The KM series coding system allows buyers to identify important product characteristics from the configuration code, including:

K – Quick coupling family

M / F – Male or female end

C / No C – With or without shut-off

L / No L – 90° elbow or straight configuration

Thread / Barb Code – Connection specification

Material Code – POM, SUS316, PEEK, PP, etc.

Color Code – White, black, natural, orange, red, green, blue, gray, yellow, etc.

Panel Mount Code – Mounting configuration

O-Ring Code – Sealing material

This modular selection system makes it easier for B2B buyers to specify a coupling configuration based on equipment design and operating conditions.

Typical B2B Selection Considerations

When purchasing KM3N8-500 or configuring a similar quick coupling, buyers should confirm:

• Required male or female connection

• Thread standard and size

• Straight or elbow configuration

• Shut-off valve requirement

• Primary material

• O-ring material

• Panel mounting requirement

• Nut material where applicable

• Product color

• Working fluid

• Operating temperature

• Operating pressure

• Chemical compatibility

• Equipment installation requirements

Selecting the correct configuration helps ensure compatibility between the coupling and the complete fluid handling system.
