Hydraulic Accessories
Connection, protection and monitoring of hydraulic circuits
Professional components for industrial and mobile hydraulic systems
Hydraulic accessories include all the elements for connection, protection and monitoring that allow hydraulic circuits to operate safely, efficiently and reliably. From tubing to fittings, from flanges to measuring instruments, right through to maintenance products, every component contributes to ensuring operating continuity and long-term performance.
Fluid System supplies a complete range of accessories designed in accordance with the main DIN, SAE and ISO design standards, selected for reliability and ease of integration in industrial and mobile hydraulic systems. We work with leading brands such as Stauff, Tognella, Wika, Fox, Rastelli Raccordi and Polyhose, ensuring build quality and operating continuity in every application. Every order is backed by technical support from our Specialists, ensuring correct sizing and compatibility with pumps, valves and hydraulic power units.
Tubing, Fittings and Clamps
Rigid and flexible tubing for low, medium and high operating pressures, fittings, pipe clamps and mounting accessories. Available solutions include:
- DIN 2353, JIC, ORFS and SAE fittings for safe, standardised connections.
- Press fittings for flexible hoses.
- SAE flanges, split flanges and adaptors for high-pressure lines.
- Pipe clamps and hose clips for fixing and vibration reduction.
In addition to products available for prompt delivery, Fluid System offers an in-house hose assembly service for every system configuration. On request, the service includes hose flushing to ensure maximum internal cleanliness and customised marking with the customer code for spare-part traceability.

ORFS Fittings
The O-Ring Face Seal (ORFS) fittings ensure leak-free sealing up to 420 bar, eliminating the risk of micro-leakage even in systems subject to vibration or thermal variation. The ISO 8434-3 standard ensures full interchangeability with other connection systems and reduces maintenance time, offering greater safety and long-term durability.
Flexible Hose Assembly Service
PROMPT DELIVERY
Fluid System’s versatility is reflected in its prompt-delivery hose assembly service: an immediate response to the maintenance and assembly needs of hydraulic systems.
CUSTOM CUTTING
In just a few minutes, we cut and assemble hoses for low, medium and high pressures. The work is carried out using state-of-the-art machinery and qualified personnel, ensuring precision, cleanliness and extremely fast turnaround times.
ON REQUEST
The service is completed with hose flushing, to remove impurities and ensure maximum internal cleanliness, and with customised marking using customer code or system reference, for full traceability. A service designed to reduce downtime and simplify spare-parts management.
Ball Valves, Flanges and Manifolds
A line of accessories for the connection and management of hydraulic flows: ball valves, SAE flanges, split flanges, swivel joints and customisable manifold blocks. These elements, manufactured in steel or stainless steel, are also available in galvanised or ATEX versions and are used on hydraulic power units, test benches, testing lines and mobile systems. The range is completed by quick couplings, pressure-control systems with test points and sealing accessories for safe, leak-free connections.

SAE Flanges
SAE flanges manufactured in accordance with SAE J518 / ISO 6162-1-2 ensure compact, safe connections in circuits up to 420 bar. Designed to withstand high dynamic loads, they represent the reference standard for connecting pumps, valves and accumulators, ensuring sealing and reliability even in demanding conditions.
Seals and Sealing Elements
Seals ensure the tightness of hydraulic connections, preventing leakage and fluid contamination. Fluid System supplies static and dynamic seals, O-rings and sealing kits for fittings, valves and components, selected for resistance to pressure, temperature and chemical compatibility with hydraulic oils. NBR, FKM, PTFE and polyurethane materials are available for industrial and mobile applications.

Hydraulic Pressure Switches
Pressure switches are essential devices for the control and safety of hydraulic circuits. They monitor fluid pressure and activate an electrical signal when the set value is reached, making it possible to manage alarm thresholds, automatic cycles or safety shut-downs. Fluid System offers traditional mechanical pressure switches and digital PSD models, suitable for industrial and mobile applications, with pressure ranges up to 600 bar and standard electrical connections in accordance with DIN EN 175301-803 or M12x1. The latest-generation PSD models integrate a high-visibility LED display, configurable digital and analogue outputs (PNP/NPN or 4-20 mA) and 330° body rotation for flexible installation even in restricted spaces. They are compatible with PLC systems, IO-Link modules and remote monitoring platforms for continuous pressure control.
Main Technical Features
- Measuring range: 0 to 600 bar.
- Accuracy ≤ ±0.5% FS.
- Protection rating: IP65 / IP67.
- ATEX versions for explosive-risk environments.
- Stainless steel body, G ¼”, G ½”, M10×1 or SAE connections.
Main Applications
- Industrial hydraulic power units and systems.
- Machine tools, presses and lifting systems.
- Special vehicles and high-pressure mobile systems.
Service and Diagnostic Products
Complementary accessories for the maintenance and management of the hydraulic system:
- Static and dynamic seals, resistant to pressure, temperature and chemical agents.
- Hydraulic oils and fluids selected for performance and compatibility with sealing materials.
- Products for sealing fittings.
- Equipment for oil transfer and filtration.
- Portable instrumentation for fluid contamination monitoring and preventive diagnostics.

Oil Filtration and Analysis
The portable filtration and analysis units allow the transfer, purification and monitoring of hydraulic oil contamination levels in accordance with ISO 4406. These solutions help prevent failures and extend the service life of pumps, valves and actuators, and now represent one of the main tools of predictive maintenance.
Typical Application Codes and Recurring Configurations
When regulating hydraulic flows, codes such as FT 1251/2-01 by Tognella are frequently searched, often also entered as FT1251/2-01 or FT1251/201. The code identifies an in-line bi-directional flow-control valve belonging to the FT1251 series, used in industrial hydraulic circuits.
