Compression fittings are a type of coupling used to connect two tubes without the need for welding, flaring, or threading, making them practical solution to create a secure and leak-tight seal. These versatile fittings are widely used across various industries, including hydraulics, oil and gas, offshore, marine, chemical, paper manufacturing, for their ease of installation and reliability in both low and high-pressure applications.
At Pegasus Hydraulics, we offer a comprehensive selection of compression fittings, including those designed to ISO 8434-1 / DIN 2353 standards, as well as options with O-ring seals for enhanced performance, and weld fittings for permanent connections.

Material: Stainless Steel
Seal Design: Utilises a single ferrule that deforms and bites into the tubing, creating a mechanical seal. Some variations may include an O-ring for enhanced sealing.
Pressure Ratings: Designed to accommodate a broad spectrum of pressure ratings, from low-pressure instrumentation lines to high-pressure hydraulic systems, ensuring suitability for diverse industrial applications.
Easy & Efficient Installation: Requires minimal tools and no specialised skills such as welding, which can significantly reduce the installation time and labour costs.
Reusable & Demountable: Some compression fittings can be easily disassembled and reassembled without compromising the integrity of the seal or damaging components, offering flexibility in system modifications and maintenance.
Versatility: By selecting different fittings to interface with each other they are highly adaptable to various fluid power systems.
Reliable & Leak-Free Connections: Engineered to provide strong, dependable, and leak-resistant connections, even in environments subject to vibration or pressure fluctuations.
