Male fitting 3/4'' - barbed straight Ø19mm

CPP barbed male fitting 3/4'' BSP with straight Ø19mm barb (Reference: 100123)

This professional barbed fitting from CPP brand represents a top-tier technical solution for all your hydraulic connection needs. Made from 30% glass fiber reinforced polypropylene, it combines the lightness of technical plastic with the robustness required for industrial and professional applications. Its 3/4'' male gas thread and 19mm diameter barbed fitting make it a versatile element for numerous hydraulic configurations.

Applications and benefits

This barbed fitting finds its place in multiple application areas. In professional irrigation, it efficiently connects flexible hoses to irrigation networks, spray systems or micro-sprinkler installations. Farmers and landscapers use it to connect flexible irrigation hoses to their fixed equipment with 3/4'' threaded outlets.

In the industrial sector, this fitting proves indispensable for cooling circuits, non-corrosive fluid transfer systems, or high-pressure cleaning installations. Construction professionals appreciate it for connecting temporary drainage hoses, suction systems or construction site water supply circuits.

Its barbed design ensures optimal sealing with flexible hoses, preventing leaks and guaranteeing constant flow. The transition between rigid thread and flexible hose is smooth, reducing mechanical stress and extending installation life.

Technical specifications and materials

The choice of 30% glass fiber filled polypropylene gives this fitting exceptional mechanical properties. This composition provides high rigidity, excellent impact resistance and remarkable durability against repeated stress. Glass fiber filling significantly improves tensile and compression strength while maintaining reduced weight.

The 3/4'' male gas thread complies with BSP (British Standard Pipe) standards, guaranteeing universal compatibility with most hydraulic equipment on the market. This tapered thread ensures progressive tightening and effective metal-to-metal sealing.

The 19mm diameter barbed fitting is precision machined to offer optimal contact surface with flexible hoses. Barbs are dimensioned to create strong mechanical grip while preserving hose integrity. This design prevents hose slippage even under high pressure.

The chemical resistance of polypropylene allows use with a wide range of fluids: drinking water, nutrient solutions, non-aggressive cleaning products, light oils and numerous chemicals common in agriculture and industry.

Installation and use

Installing this barbed fitting is done in two distinct steps. For the threaded side, use a flat wrench or pipe wrench to screw the fitting onto the receiving equipment. Apply moderate tightening torque, as polypropylene requires less force than metal fittings. Using Teflon tape or sealing paste is recommended to perfect the seal.

For the barbed side, push the flexible hose onto the barb until it stops. The barbs should slightly embed into the hose inner wall. Use soapy water as lubricant to facilitate insertion. Then install a hose clamp suitable for the hose diameter, positioning it on the barbed area to maximize sealing.

During operation, periodically check clamp tightness, particularly during the first months of use. Temperature variations can cause slight material relaxation. Avoid bending the hose in immediate proximity to the fitting to preserve mechanical stress.

For maintenance, cleaning with clear water is generally sufficient. In case of fouling, use a soft brush with non-aggressive detergent. Polypropylene resists UV well, but storage away from direct sunlight extends its outdoor life.

Expert advice and product synergies

To optimize this fitting's performance, combine it with quality stainless steel hose clamps, resistant to corrosion and offering uniform clamping. Worm drive clamps 16-25mm are perfect for 19mm inner diameter hoses.

In irrigation installations, combine this fitting with reinforced anti-UV and anti-algae hoses to create a durable system. For industrial applications, favor food-grade hoses if contact with consumable products is possible.

Seasonal tip: before winter, completely drain circuits using this type of fitting. Although polypropylene resists freezing, frozen water expansion can damage connected hoses or create overpressure in the system.

For professionals, build stock of different barbed diameters (16, 19, 25mm) with corresponding threads. This modular approach allows quick response to maintenance needs and installation extensions.

Error to avoid: never force plastic thread tightening. Excessive torque can crack the fitting or damage the receiving equipment thread. The rule is "hand tight plus a quarter turn with wrench".

When connecting to equipment subject to vibrations (pumps, compressors), insert a flexible hose section long enough to absorb movements and preserve threaded fitting integrity.
