Product catalog summary

Overview

This document is a comprehensive technical reference for hydraulic adapters, connectors, and fittings conforming to DIN 24° and ISO standards. It covers a wide range of product categories, thread types, pressure ratings, dimensions, and sealing methods, aimed at engineers and procurement specialists involved in hydraulic system design and maintenance.

1. Product Categories and Types

Nuts (ISO 8434-1): Metric threaded nuts available in various sizes (4 mm to 42 mm tube diameters) and pressure ratings (100 to 630 bar).
Cutting Rings (ISO 8434-1): Cutting rings matching tube diameters from 4 mm to 42 mm, supporting pressures up to 630 bar.
Male Stud Connectors: Offered with multiple thread standards including BSPP, Metric fine, UNF, BSPT, Metric tapered, and NPTF tapered threads. Some feature elastomeric sealing (Form E ISO 1179-2) for enhanced leak prevention.
Unions and Reducers: Straight unions, reducers, 90° elbows, tees, cross unions, bulkhead unions, and swivel unions for flexible hydraulic configurations.
Adjustable Elbows and Tees: 45° and 90° adjustable stud elbows and run tees with BSP, BSPP, UNF, and ORFS-Metric threads for installation flexibility.
Plugs and Welding Components: Blanking plugs, male plugs, pipe plugs with O-ring seals, welding bosses, welding straight bulkheads, and welding nipples with O-ring seals for permanent or temporary sealing.
Gauge Connectors: Standard and swivel gauge connectors designed for pressure measurement integration.

2. Technical Specifications

Product Number: Unique identifiers for ordering and reference.
Tube Diameter (Ø tube): Ranges from 4 mm to 42 mm depending on product type.
Type and Pressure Rating (W.P.): Series designations (LL, L, S) with working pressures from 100 bar up to 630 bar.
Thread Type and Size: Includes Metric, BSPP, UNF, BSPT, NPTF threads with detailed dimensions.
Dimensions: Lengths (L, L1, L2, L3, L4), wrench sizes (CH1, CH2, CH3), diameters, and other critical measurements in millimeters.
Weight: Mass per unit ranging from a few grams to over 1 kg depending on size and type.

3. Standards and Compliance

Products comply with international standards such as ISO 8434-1, ISO 1179-2, ISO 9974-2, ISO 6149, ISO 11926, and DIN 3852.
Thread forms and sealing types conform to ASME B1.20.1 and ISO norms to ensure compatibility and safety.

4. Seal Types and Materials

Conical thread sealing per ASME B1.20.1 for tapered threads ensures reliable leak-tight joints without additional sealants.
Elastomeric seals (Form E ISO 9974-2) are used in some connectors for enhanced sealing performance.
Standard seal materials include FKM, with optional seals in NBR and EPDM to suit different chemical and temperature environments.
