Rotating 90° Express Fitting in Brass - Patented Model ® - Supplied with Pre-Fitted Seal

Rotating 90° Express Fitting in Die-Cast Brass - Patented Model ® (Reference: 526)

This Ezfitt rotating 90° Express fitting represents technical excellence in the field of hydraulic and pneumatic fittings. Designed according to French standard NF E29-573 with a claw spacing of 41 mm, this patented model guarantees full compatibility with all fittings of the same standard. Its die-cast brass construction and double NBR O-ring sealing system make it a component of choice for demanding professionals.

Applications and Benefits

This rotating 90° Express fitting meets the specific needs of installations requiring a right-angle direction change with the possibility of free rotation. It proves indispensable in professional irrigation systems, industrial pneumatic installations, and hydraulic circuits where space is limited.

Landscapers and irrigation installers particularly appreciate its ability to facilitate connections in difficult corners, while pneumatic technicians value its robustness against high pressures up to 10 bar. Its rotating function prevents mechanical stress on pipes, thus extending the service life of the installation.

Compatible with water and compressed air, this fitting is perfectly suited for seasonal applications thanks to its resistance to temperatures from -10°C to +70°C.

Technical Specifications and Innovation

The patented design of this fitting reflects Ezfitt's innovation in the field of Express fittings. Die-cast brass offers exceptional resistance to corrosion and mechanical stress, guaranteeing superior longevity compared to standard alloys.

The sealing system with a double NBR O-ring (Nitrile Butadiene Rubber) ensures a perfect seal even under pressure. This technology maintains the seal during rotations, preventing leaks and malfunctions.

The machined flanged ribbed tail facilitates assembly with a hose clamp (reference 515/1515), guaranteeing a secure and durable assembly. The dimensions strictly comply with French standard NF E29-573, ensuring perfect interchangeability with existing installations.

Its nominal pressure rating PN 10 bar makes it compatible with the majority of professional applications, while its extended temperature range allows use in all seasons.

Installation and Practical Use

Installing this rotating 90° Express fitting requires a suitable hose clamp (reference 515/1515) to secure the ribbed tail onto the pipe. The integrated flange facilitates positioning and evenly distributes the clamping pressure.

Before fitting, check the condition of the double NBR O-ring seal supplied pre-fitted. Thoroughly clean the contact surfaces to avoid any contamination that could compromise the seal. Assembly is carried out without special tools, facilitating maintenance operations.

The rotating function allows the fitting to be oriented in the desired position after installation, avoiding torsional stress on pipes. This feature proves particularly useful in confined spaces or complex installations.

For maintenance, periodic visual inspection of the seals and general condition of the fitting is sufficient. Die-cast brass requires no special treatment, but avoid sudden thermal shocks to preserve the integrity of the seals.

Tips, Synergies and Expert Advice

To optimise the performance of this rotating 90° Express fitting, always pair it with quality hose clamps (reference 515/1515). Incorrect tightening can compromise the seal and damage the ribbed tail.

In irrigation installations, combine this fitting with Express valves from the same series to create modular circuits that are easy to disassemble. This approach facilitates winter maintenance and allows quick modifications to circuits.

For pneumatic applications, provide a purge system upstream to remove moisture that could damage the NBR seals over time. Avoid sudden overpressures that could exceed the PN 10 bar limit.

Professionals recommend maintaining a stock of spare parts, particularly NBR O-ring seals, to ensure continuity of service. Standardisation according to NF E29-573 guarantees the availability of components.

In outdoor environments, protect the fittings from prolonged frost which could weaken the seals, even though the temperature range goes down to -10°C. Complete draining remains the best protection against freezing.
