Overview
ISO 7824:1986 is an international standard established by the International Organization for Standardization (ISO) that specifies the design and dimensions of lubrication nipples used in shipbuilding and marine structures. The standard focuses on two main types of hydraulic lubrication nipples-cone and flat types-which are essential for the effective lubrication of machine parts on marine vessels. By standardizing nipple types and dimensions, ISO 7824 helps reduce the variety of grease-pumps required, improving maintenance efficiency and ensuring compatibility across shipbuilding applications.
Key Topics
Scope and Purpose
ISO 7824 is aimed at defining the dimensions and types of lubrication nipples suitable for hydraulic systems in shipbuilding and marine structures. Limiting nipple variations helps streamline lubrication processes and equipment usage.Types of Lubrication Nipples
- Cone Type Nipples (Types 1, 2, 3):
These have tapered threads and are designed for general lubrication use. Their dimensions are derived from ISO 3799, which covers hydraulic lubrication fittings in textile machinery but is applicable here for marine purposes. Cone nipples are sometimes referred to as "hydraulic grease nipples." - Flat Type Nipples (Type 4):
Also known as "buttonhead nipples," flat type nipples are recommended where larger lubricant spaces need to be filled, such as lifting appliances.
- Cone Type Nipples (Types 1, 2, 3):
Dimensions and Specifications
- Cone Type Nipples: Dimensions include width across flats, screw thread size (M10 x 1 metric thread standard as per ISO 261), length, gauge diameter, and lateral distance.
- Flat Type Nipples: Characterized by detailed measurements such as width across flats, screw thread, chamfer dimensions, height, and length, also conforming to ISO metric screw thread standards.
Material and Finish
Lubrication nipples and springs are typically made from steel, with electroplating via electrolytic galvanization for corrosion resistance. Alternative materials like phosphor bronze or brass for body, ball, and spring components may be specified with manufacturer agreement.Designation and Identification
The standard defines a structured system for designating lubrication nipples that includes:- The term “lubrication nipple”
- The ISO number (ISO 7824 for flat types, ISO 3799 for cone types)
- The nipple type number (1–4)
- Screw thread size (where applicable)
- Material description
- Surface finish information (if other than galvanized)
Applications
ISO 7824:1986 lubrication nipples are highly relevant for:
- Shipbuilding Industry: Facilitating proper hydraulic lubrication of ship machinery, deck equipment, and marine structures ensures operational reliability and reduces maintenance downtime.
- Marine Maintenance and Repair: Standardized nipples ease inventory management for grease pumps and replacement parts onboard vessels and in shipyards.
- Industrial Hydraulic Systems: Although developed for shipbuilding, the standard’s nipple types can also be useful in other heavy machinery requiring reliable lubrication fittings.
- Safety and Compliance: Using standardized nipples ensures conformity with international marine equipment regulations and promotes safety by preventing incorrect part usage.
Related Standards
- ISO 3799: Covers hydraulic lubrication fittings for textile machinery; provides the dimensional basis for cone-type nipples referenced in ISO 7824.
- ISO 261: Defines metric screw threads standards used for the screw thread dimensions in lubrication nipples.
- ISO 7924: Relates to flat-type lubrication nipples and applies when designating flat nipple types under ISO 7824.
Practical Value
Adhering to ISO 7824:1986 provides practical benefits in terms of:
- Enhanced interchangeability of lubrication nipples across different marine vessels and equipment.
- Streamlined maintenance processes by limiting the variety of grease guns and pumps required.
- Improved durability and corrosion resistance through specified materials and finishes.
- Facilitated supply chain management with clear designation and dimension standards for lubrication fittings.
Integrating ISO 7824 standards contributes to the robust design and upkeep of hydraulic lubrication systems essential for reliable ship operation and marine structural integrity.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7824 was prepared by Technical Committee ISO/TC 8,
Shipbuilding and marine structures.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
