Express Fitting with Machined Serrated Tail and Flange without Seal

Express Fitting with Machined Serrated Tail and Flange - Reference: 710

This Ezfitt heavy-series Express fitting represents the excellence of French manufacturing in the field of professional fittings. Designed according to the rigorous French standard NF E29-573, it guarantees perfect compatibility with all fittings compliant with this standard. Its forged brass construction gives it exceptional resistance and remarkable longevity in the most demanding industrial environments.

Benefits and Applications

This Express fitting finds its place in numerous professional and industrial applications. It excels particularly in pressurised water installations and compressed air circuits, supporting pressures up to 10 bar. Plumbing, pneumatics and industrial professionals appreciate it for its ability to provide fast and secure connections.

Its machined serrated tail enables optimal fixing with flexible hoses, while its flange facilitates assembly with a clamp. This ingenious design considerably reduces installation time while guaranteeing a perfect seal. Agriculture, professional irrigation, industrial maintenance and mechanical workshops are its main areas of use.

Technical Specifications and Innovation

The forged brass construction forms the core of this fitting's quality. This hot-forging manufacturing process guarantees a homogeneous and dense structure, offering superior resistance to mechanical stress and corrosion. The selected brass alloy withstands service temperatures between -10°C and +70°C.

The serrated tail is precision-machined to ensure maximum adhesion to the hose. The precisely calibrated serrations create a mechanical anchor that prevents any slipping, even under high pressure. The integrated flange facilitates the positioning of the clamp and evenly distributes the clamping forces.

In accordance with standard NF E29-573, the jaw span measures precisely 41 mm, ensuring universal compatibility with all fittings in the same series. This standardisation prevents installation errors and facilitates maintenance.

Installation and Practical Use

Installing this Express fitting is carried out in a few simple but crucial steps. Begin by checking that the hose to be connected has an inner diameter compatible with the serrated tail. Thoroughly clean the end of the hose to remove any impurities that could compromise the seal.

Slide the hose onto the serrated tail, ensuring it fully covers all the serrations up to the flange. This operation may require some effort, particularly with new hoses or in cold weather. A light lubrication with soapy water can ease the operation.

Then position the 515/1515 clamp (sold separately) against the flange and gradually tighten in a cross pattern to ensure even pressure distribution. Excessive tightening could damage the hose, while insufficient tightening would compromise the seal.

For maintenance, periodically check the condition of the fitting and hose. Verify the absence of leaks and proper tightening of the clamps. Regular cleaning with warm water and a mild detergent will preserve the appearance and properties of the brass.

Expert Tips and Product Synergies

The efficiency of this Express fitting can be optimised by carefully selecting complementary components. Always pair it with quality 515/1515 clamps to ensure a lasting seal. Avoid budget clamps that may deform under pressure.

In professional irrigation installations, this fitting pairs perfectly with our high-pressure hoses and Gardena irrigation systems. For pneumatic applications, choose hoses specifically designed for compressed air to avoid expansion issues.

Expert tip: always keep a few spare fittings in stock. Their compact size and durability make them ideal parts for emergency repairs. In winter, protect your installations from frost by draining the circuits or using antifreeze solutions compatible with brass.

For professionals working on site, this fitting withstands cement splashes and dusty environments perfectly. Cleaning remains straightforward even after exposure to harsh conditions. Remember to regularly disassemble and clean your Express fittings to maintain optimal performance.
