Press gland - internal thread, 3/4" F x 26

Product detailed description

Press glands are essential in heating and plumbing systems where rigid connections between plastic and metal components are required. This model is suitable for applications such as domestic hot water supply, underfloor heating and central heating circuits. Installers working with ALPEX pipes often use such fittings to transition to threaded components like valves, meters or radiators. The design allows for secure, leak-tight connections without the need for soldering or threading the plastic pipe.

The fitting is installed using a press tool compatible with the B-F-TH jaw type. It is particularly useful in retrofitting or new builds where a transition from plastic to metal is necessary. The compact size and robust construction make it ideal for tight spaces behind walls or in mechanical rooms. The nickel-plated brass body ensures resistance to corrosion, while the EPDM sealing ring provides flexibility and durability under thermal expansion and contraction.

Technical parameters

Material	nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.119 kg
Code	510014
Brand	IVAR

The nominal pressure rating of PN 10 means the fitting can withstand up to 10 bar at standard temperatures. The maximum operating temperature of +120°C is important when selecting this component for hot water or heating applications. These parameters ensure the fitting is suitable for medium-pressure systems with moderate thermal conditions. The material combination of nickel-plated brass and stainless steel clamping sleeve offers high resistance to mechanical stress and environmental factors.

Installation and connection

To install the press gland, first ensure the ALPEX pipe is cut cleanly and free of burrs. Insert the pipe into the fitting until it reaches the stop mark. Use a press tool with the correct jaw type to apply the required pressure around the pipe and sleeve. After pressing, verify the connection by checking for any movement between the pipe and fitting. Common installation errors include using incorrect jaw types, insufficient or excessive pressing force, or failing to align the pipe correctly before pressing. Always confirm the fit against a test pressure before commissioning the system.

Compatibility and accessories

This press gland is specifically designed for use with ALPEX pipes and requires a compatible press tool with jaws of type B-F-TH. For complete system integrity, ensure all adjacent fittings and components are also rated for the same pressure and temperature conditions. Additional items such as press tools, pipe cutters and deburring tools may be needed during installation. There are no alternative or related products listed for this item.

Technical background for designers

This press gland operates by compressing the stainless steel sleeve around the outer diameter of the ALPEX pipe, creating a mechanical bond. The nickel-plated brass body provides structural support and ensures compatibility with metal piping systems. The EPDM sealing ring compensates for minor misalignments and thermal movements. In system design, it is important to account for the expansion characteristics of the plastic pipe and the rigidity of the metal components. The PN 10 rating and +120°C limit should be considered when determining the overall system pressure and thermal load distribution.

Service and operation

Once installed, the press gland requires no active maintenance. However, regular visual inspections should be carried out to check for signs of mechanical stress, corrosion or leakage. Any damage to the press marks or the clamping sleeve indicates the need for replacement. The long-term performance of the fitting depends on the quality of the initial installation and the stability of the surrounding system conditions.

Frequently asked questions

Can this press gland be used with copper pipes?
No, it is specifically designed for ALPEX pipes and will not provide a secure connection with copper.

Is the EPDM sealing ring replaceable?
No, the sealing ring is integrated into the fitting and cannot be replaced separately.

Can this fitting be used in steam systems?
No, the maximum operating temperature of +120°C limits its use to hot water and heating systems, not steam applications.
