JIS B 2403-2009 PDF

Full title and description

JIS B 2403:2009 — V packings. This Japanese Industrial Standard specifies requirements, dimensions, test methods and related provisions for V-shaped packings (V‑packings / V‑rings) used in general oil‑hydraulic equipment that employ petroleum‑base hydraulic oil.

Abstract

This standard defines V packings for general oil‑hydraulic machines and instruments using petroleum‑base hydraulic oil, covering product definitions, material and dimensional requirements, mounting/combination guidance and test procedures to confirm performance and acceptability.

General information

• Status: Current (listed as current / reaffirmed in publisher records; history shows a reaffirmation in 2013).
• Publication date: 20 February 2009 (JIS B 2403:2009).

• ICS / categories: 23.100.60 — Filters, seals and contamination of fluids (fluid power / seals).
• Edition / version: JIS B 2403:2009 (current edition).
• Number of pages: 15 pages (standard document length).

Scope

This JIS applies to V packings intended for general oil‑hydraulic equipment that use petroleum‑base hydraulic oil. It covers the definition of V packings, dimensional systems and mounting (combinations of V packings), material and performance requirements, and required test methods and acceptance criteria for those packings. The standard was revised to update test items and test conditions to reflect changes in referenced standards.

Key topics and requirements

• Definitions and classification of V packings (profiles, types and nominal sizes).
• Dimensional specifications and recommended groove/adapter dimensions for correct installation and combination heights.
• Material specifications and selection guidance for elastomeric and fabric‑reinforced V packings appropriate for petroleum‑base hydraulic oil.
• Test methods and conditions (hardness, dimensional stability, aging, endurance and leakage/performance tests) and acceptance criteria.
• Marking, packaging and identification requirements to ensure traceability and correct use.
• Guidance on combinations/stacking of V packings (installation heights and recommended arrangements) and limits of application.
• Reference/compatibility notes noting that, at the time of revision, no directly corresponding international standard had been established.

Typical use and users

Typical users include hydraulic component manufacturers, sealing‑element producers, designers of hydraulic cylinders and actuators, maintenance and reliability engineers, procurement/specification writers and test laboratories. The standard is used to specify, inspect and test V packings for pumps, cylinders, valves and other hydraulic machinery operating with petroleum‑base hydraulic fluids.

Related standards

Related JIS documents include the earlier edition JIS B 2403:1995 (superseded by the 2009 edition) and other JIS in the B‑240x family addressing sealing elements (for example the JIS B 2401 series for O‑rings and related seals). Referencing and cross‑references in JIS B 2403:2009 reflect those related JIS documents.
