Express Fitting with Machined Serrated Tail and Flange with Seal

The Ezfitt Express Fitting with Machined Serrated Tail and Flange with Seal (Reference: 510) represents the excellence of French professional pipe fitting. This heavy-duty series fitting, designed according to NF E29-573 standard, guarantees perfect compatibility with all Express fittings of the same standard. Its forged brass construction and advanced technical design make it the preferred choice for industrial, agricultural and maintenance installations requiring reliability and durability.

Applications and fields of use

This Express fitting finds its place in numerous professional applications where robustness and sealing are paramount. It is perfectly suited to industrial water networks, compressed air distribution systems in workshops and factories, as well as agricultural installations for irrigation and livestock watering.

Maintenance professionals particularly appreciate its ease of installation and compatibility with all Express fittings to French standards. In the construction sector, it proves indispensable for temporary site connections, mobile compressor connections and high-pressure cleaning systems. Its flange design allows secure mounting on all types of flexible hoses, guaranteeing perfect sealing up to 10 bar.

Technical characteristics and innovation

The design according to NF E29-573 standard with a 41 mm claw spacing ensures universal compatibility with all Express fittings in the same family. The forged brass used in its construction offers exceptional resistance to corrosion and mechanical stress, guaranteeing remarkable longevity even in the most demanding environments.

The precision-machined serrated tail allows for optimal hose grip, preventing any risk of accidental disconnection under pressure. The integrated type A lip seal in NBR (nitrile butadiene rubber) ensures perfect sealing with a 15 mm diameter bore. This technical design allows it to withstand pressures up to 10 bar while maintaining flexibility of use across a temperature range of -10°C to +70°C.

The integrated flange is a key safety element, allowing the use of clamp reference 515/151 for permanent and secure mounting.

Installation and implementation

Installation of the Express 510 fitting is carried out in a few simple steps thanks to its optimised design. Begin by checking the cleanliness of the hose and making a straight, clean cut. The serrated tail must be fully inserted into the hose until it butts against the flange.

To ensure optimum sealing, position clamp 515/151 on the hose before inserting the serrated tail, then tighten it firmly against the flange. This mounting method guarantees exceptional mechanical hold even under high pressure. As the NBR seal is pre-fitted, no additional handling is required to ensure sealing.

For maintenance, periodic inspection of the seal condition is recommended, particularly in applications where pressure cycles are frequent. Disassembly is carried out simply by loosening the clamp and removing the hose from the serrated tail.

Expert advice and optimisation

To maximise the performance of your installation, always pair this fitting with the clamp reference 515/151 specially designed for its flange. This combination guarantees maximum safety and prevents any risk of disconnection under pressure.

In installations subject to significant thermal variations, allow for a slight expansion gap to avoid excessive stress on the fittings. For compressed air applications, consider installing an oil separator upstream to preserve the longevity of the NBR seal.

Experienced professionals recommend keeping a stock of spare fittings for critical installations, enabling effective preventive maintenance. In corrosive environments, although brass offers excellent resistance, regular visual inspection allows you to anticipate any necessary replacement.

Installation tip: use a compatible lubricant (glycerine or neutral soap) on the serrated tail to facilitate insertion into rigid hoses, while taking care not to contaminate the sealing gasket.
