Product catalog summary

Overview

This document provides comprehensive technical specifications for the GE Series VGA Hydraulic Quick Couplings, designed according to ISO 14541 standards. These screw-to-connect couplings are intended for hydraulic applications and are available in carbon steel and stainless steel variants, with multiple thread standards to ensure broad compatibility.

1. Specifications and Materials

Materials: Carbon Steel (SS 1.0737) with galvanization and Stainless Steel (SS 1.4404) for corrosion resistance.
Seal Options: NBR (B) standard and FKM (E) available on request, selected based on fluid compatibility and temperature.
Sizes: Nominal diameters (DN) range from 6 to 35 mm.
Pressure Ratings: Rated up to PN420 (42 MPa / 6090 psi) for most sizes; some larger sizes rated at PN35 (35 MPa / 5075 psi).

2. Product Types and Standards

Couplings feature screw-to-connect male and female ends.
Conform to ISO 14541 for quick couplings.
Thread standards include ISO 1179-1 BSPP and ISO 8434-1 (DIN 2353) metric threads, with both standard and bulkhead versions.
Bulkhead couplings designed for panel or wall mounting with specific dimensional adaptations.

3. Product Coding and Identification

Each coupling is identified by a code indicating coupling type, nominal size (DN), material, and seal type. For example, "QC 1/2 F/M DN12,5 1 B" denotes a quick coupling, 1/2 inch female/male, DN12.5, carbon steel (1), with NBR seal (B).

4. Dimensional and Performance Data

Nominal Diameter (DN): 6.3 to 35 mm.
Pressure Ratings (PN): Mostly 42 MPa, some at 35 MPa.
Dimensions: Key parameters include diameter (ØA), length (C), thread length (z), wrench size (ch), thread diameter (ØM), and additional thread parameters for metric threads.
Weight: Varies by size and material, approximately 0.1 kg to 1.56 kg.
Item Codes: Unique codes facilitate precise ordering (e.g., NC15L03S003 for stainless steel male coupling DN18).

5. Thread Variants and Compatibility

BSPP threads per ISO 1179-1.
Metric threads per ISO 8434-1, including short (S), long (L), and bulkhead versions.
Multiple thread sizes available (e.g., M14x1.5, M18x1.5, M26x1.5, M30x2, M36x2, M42x2, M48x2) to ensure compatibility with diverse hydraulic systems.

6. Additional Features and Notes

Patented versions with integrated ball valves are available.
Other thread types can be supplied upon request.
The manufacturer reserves the right to modify dimensions without prior notice.

7. Best Practices and Recommendations

Select coupling material based on environmental conditions and corrosion resistance needs.
Choose seal material according to fluid type and operating temperature.
Verify thread type and size to ensure proper fit with existing hydraulic components.
Adhere strictly to pressure ratings to maintain system safety and performance.
Use item codes and dimensional tables carefully for accurate ordering and installation.
