Technical Catalog Overview

This document serves as a comprehensive technical catalog detailing threaded fittings and seals compliant with ISO standards, primarily ISO 6153, ISO 6154, ISO 7-1, and ISO 228-1. It is intended for engineers and procurement specialists to ensure proper selection, certification compliance, and application of fittings and seals in fluid and mechanical systems.

Main Sections

1. Threaded Fittings According to ISO Standards

This section catalogs threaded fittings conforming to ISO standards, providing detailed product codes, dimensional data (including Rp, G, d1, d2, L, L1, L2, H, E, CH, PN), and weights in grams. Fittings are categorized by type and size, facilitating precise selection based on application requirements.

2. Seals and Certification

Seals specified are primarily EPDM type, which is mandatory for certification validity. Certifications and approvals apply strictly to products listed officially or holding valid certificates. The document emphasizes that certification status is product-specific and must be verified against official listings.

3. Material Codes and Variants

The catalog identifies material codes for EPDM and FKM seals, highlighting their compatibility and sealing properties. Matching material codes to application needs is critical for ensuring sealing performance and certification compliance.

4. Dimensional Tables

Multiple detailed tables provide essential dimensional parameters for various fitting types, including:

• Thread codes and designations
• Dimensions such as diameters (d1, d2), lengths (L, L1, L2), heights (H), wrench sizes (CH), and pitch (P)
• Nominal pressure ratings (PN)
• Weights in grams

These tables are vital for selecting fittings that meet precise dimensional and material specifications.

5. Ordering and Reference Codes

Ordering codes and references are provided for each fitting and seal type, enabling accurate procurement and ensuring specification compliance.

Critical Information and Best Practices

• Use EPDM seals exclusively to maintain certification validity.
• Verify product certification status through official listings or certificates before application.
• Adhere to ISO standards (ISO 6153, ISO 6154, ISO 7-1, ISO 228-1) for compatibility and compliance.
• Carefully consult dimensional tables to select fittings matching required specifications.
• Match material codes (EPDM, FKM) to application requirements to ensure sealing effectiveness.
• Recognize that all dimensions are nominal and subject to change without notice.
• Understand that the document is for guidance only and does not constitute a sale offer or warranty.
• Ensure compliance with local laws and regulations when applying the information.

Certification and Compliance

Certifications and approvals are valid only for valves and fittings with ISO threads. The certification status is strictly linked to the product’s official listing or certificate. Users must confirm certification validity before use.

Important Notes and Recommendations

• Descriptions and illustrations are for guidance only.
• Dimensions are nominal and may change without prior notice.
• Information is provided "as is" without warranty.
• Users must ensure legal compliance in their jurisdiction.
• Reproduction or distribution of the document without consent is prohibited.
