O-Rings and Seals

Product catalog summary

Overview: The document is a catalog from Parker Hannifin Corporation's Tube Fittings Division, focusing on O-rings and seals for hydraulic and pneumatic systems. It covers specifications, material selection, and application guidelines for various seals.

Material Selection: Standard O-rings are made from 90 durometer hard nitrile (Buna-N), ideal for high-pressure static applications. High-temperature fluorocarbon (Parker compound #V0894) is available for higher temperature needs. A selection chart helps choose O-ring materials based on fluid compatibility, temperature, and pressure.

Specifications: The catalog details various O-ring types, including EO Swivel O-Ring, ORFS O-Ring, and Metal Seal for Banjo Fittings, with dimensions, material options, and standards like SAE, ISO, and JIS.

Applications: Detailed tables assist in selecting the right O-ring size and material for applications such as hydraulic systems, climate control systems, and fuel cells, emphasizing material compatibility with environmental conditions.

Key Recommendations: Use 90 durometer hard O-rings for pressures of 1500 psi or higher. Conduct tests to ensure compatibility with fluid, temperature, pressure, and environmental conditions before final selection.

Tables and Data: Extensive tables list part numbers, dimensions, and material options for various O-ring types, crucial for selecting the correct O-ring for specific applications.

Specifications:

Metal Seals for Banjo Fittings: Available in steel and stainless steel, with examples like DKA1/8CFX (steel) and DKA1/871X (stainless steel).
Bonded Seals for Banjo Fittings: Specify size and material, with examples like KDS 12X (standard steel with NBR) and KDS 1271 (stainless steel with PTFE).
O-Rings: Available in NBR (90-durometer Nitrile) and FKM (85-durometer Fluorocarbon) compounds, with dimensions and part numbers for various sizes and series.

Procedures:

Ordering: Specify size and material when ordering seals and fittings, with examples provided for clarity.

Standards and Recommendations:

Material Standards: NBR is standard for most seals, with FKM as an optional compound for specific applications.
Dimensional References: All dimensions are for reference only and subject to change.

Key Data from Tables:

O-Ring Dimensions: Detailed dimensions for O-rings, including diameter and height for both NBR and FKM compounds.
Flange Series: Includes LK35, LK40, and LK55 with corresponding O-ring dimensions.

Critical Information:

Material Selection: Choose appropriate material based on application requirements, considering pressure and temperature.
Compatibility: Ensure seal compatibility with hydraulic fluids used in the system.
