Overview of PLT Series Couplings

The document presents technical details and specifications for the PLT series hydraulic couplings, specifically models PLT1, PLT4, PLT5, PLT6, PLT7, and PLTX. These couplings conform to ISO 16028 standards and are designed primarily for flat face steel connections.

Standards and Specifications

• ISO 16028 Compliance: The couplings meet the ISO 16028 standard for flat face hydraulic quick couplings, ensuring compatibility and performance.
• Pressure Rating: Rated for 350 bar operating pressure, suitable for high-pressure hydraulic applications.
• Material: Constructed from steel, providing durability and resistance under demanding conditions.
• High Resistance Variant: Certain models, such as the flat face male for hammers (PLT5), are designed for enhanced resistance to withstand hammering impacts.

PLT5 Model Specifics and Assembly Instructions

The PLT5 model is detailed with a focus on the male coupling component, which is used in hammer applications. The document includes assembly instructions for colored rings that correspond to specific part numbers, facilitating correct identification and installation.

• Tool Codes and Sizes: Examples include PLT.025.8X3 for DN25 (ISO 19) and PLT.031.8X3 for DN30 (ISO 25).
• Colored Rings: Multiple color-coded rings are listed (e.g., codes ending with 803, 813, 823, etc.), all made from polypropylene (PP), used to identify and assemble the male coupling correctly.
• Assembly Procedure: The male coupling is pushed down onto the colored ring to complete the assembly, ensuring a secure and standardized connection.

Key Recommendations and Best Practices

• Use the color-coded ring system to avoid assembly errors and ensure compatibility with corresponding female couplings.
• Adhere strictly to ISO 16028 standards for installation and maintenance to guarantee safety and performance.
• For hammer applications, select the high resistance PLT5 male coupling variant to withstand mechanical stresses.
