FLAT FACE

Product catalog summary

Overview

This document provides comprehensive technical specifications for the GE Series hydraulic quick couplings designed according to the ISO 16028 Flat Face standard. These couplings enable quick connect/disconnect functionality in hydraulic systems while minimizing fluid loss and contamination.

1. Product Composition and Types

Coupling Type: Flat face quick couplings compliant with ISO 16028.
Models and Sizes: Nominal diameters (DN) ranging from 6.3 mm (1/4") to 25 mm (1 1/2"), with larger sizes available on request.
Materials: Carbon Steel (CS) with Zinc-Nickel plating and Stainless Steel (SS) variants for corrosion resistance.
Seal Materials: Standard NBR (B) seals; FKM (E) seals available upon request for enhanced chemical resistance.
Additional Features: Patented versions with integrated ball valve quick coupling; color-coded plugs and caps (blue, yellow, red, green) for protection when disconnected.

2. Standards and Thread Types

ISO 16028 Flat Face coupling standard ensures leak-free, contamination-minimized connections.
Compatible thread standards include:

ISO 1179-1 BSPP (British Standard Parallel Pipe)
ISO 8434-6 BSPP
ASME B1.20.1 NPT (National Pipe Thread)
ISO 11926-1 (SAE J1926-1) ORB (O-Ring Boss)
ISO 8434-1 (DIN 2353) for short and long tube fittings, including bulkhead versions
SAE J514 JIC fittings

3. Product Coding and Identification

The coding system identifies coupling type, connection thread and size, body material, seal material, gender (male/female), and nominal diameter. For example:

Body material codes: 1 for Carbon Steel (1.0737), 4 for Stainless Steel (1.4404)
Seal codes: B for NBR, E for FKM

4. Technical Specifications

Nominal Diameter (DN): 6.3 mm to 25 mm (1/4" to 1 1/2")
Pressure Ratings (PN): Up to 42 MPa (420 bar / 6090 psi), depending on size and material
Dimensions: Detailed parameters including overall length (ØA), connection length (C), diameter (Ød), wrench size (ch), and thread diameter (ØM) provided in metric and imperial units
Weight: Specified in kilograms and pounds for each variant
Item Codes: Unique ordering codes for each coupling variant

5. Material Variants

Carbon Steel (CS): Zinc-Nickel plated for corrosion resistance, suitable for general hydraulic applications
Stainless Steel (SS): Corrosion-resistant option for demanding environments

6. Additional Notes and Recommendations

Other thread types and sizes above DN25 are available on request, allowing customization
The manufacturer reserves the right to modify dimensions without prior notice; users should verify current specifications before ordering
Seal material FKM is recommended for enhanced chemical resistance
Use plugs and caps to protect couplings when disconnected
Adhere strictly to pressure ratings to ensure safe operation
Confirm thread type and size compatibility before selection
Use stainless steel variants in corrosive environments
Proper wrench sizes are specified for installation and maintenance

7. Summary of Critical Information

Couplings conform to ISO 16028 Flat Face standard, ensuring leak-free and contamination-minimized hydraulic connections
Wide range of sizes and thread standards (BSPP, NPT, ORB, JIC, DIN) for versatile system integration
High pressure ratings up to 42 MPa suitable for demanding hydraulic applications
Material options (Carbon Steel and Stainless Steel) allow selection based on environmental and corrosion resistance needs
Detailed dimensional and weight data support precise engineering design, procurement, and maintenance

Conclusion

This document serves as a detailed technical reference for selecting and specifying GEMHYDRAULIC ISO 16028 flat face hydraulic quick couplings. It provides essential information on product types, standards, materials, pressure ratings, dimensions, and ordering codes. Users are advised to verify the latest specifications due to possible dimensional changes and to select coupling variants based on application requirements including thread compatibility, pressure rating, and environmental conditions.
