Yes, however mechanical compression using an olive or threaded joints should not be embedded.

The locating collar ensures that the pressing sleeve is correctly positioned in the pressing jaw.

The Henco Press Check is a measuring instrument that checks the press finding and verifies whether the pressing has been carried out correctly.

V, M and SA profile’s can be used to ensure correct jointing

The press bench for Super Sizes, this can cut, deburr and press pipes with diameter 75mm and 90mm with all attachments required in one place.

No, this is not permitted by law.

No, at high levels chlorine vapours may corrode the stainless steel press fittings. Exposure can be avoided by protecting the press sleeves with a protective tape wrap

Yes, for example as ground pipes. In this case, we recommend combining the Henco standard multilayer pipe with the PVDF press fittings. It is best to protect the pipe additionally with, for example, a PVC protective tube. Please note that Henco inspection certificates only apply to indoor installations.

Yes, at a maximum pressure of 10 bar and ambient temperatures between -10°C and 40°C.

Only if the soil does not contain any chemicals and the pipe is protected from external damage. Brass fittings should always be protected from corrosion and we also recommend protecting PVDF fittings from external impact with, for example, a PVC pipe.

The minimum temperature for Henco multilayer pipes and PVDF press fittings is -20°C. For solid plastic pipes, the minimum temperature is 7°C.

Henco multilayer pipes and PVDF press fittings with gas marking may be used for gas. Please note that gas application is only allowed in countries where a Henco gas inspection and certificate is available.

Yes, when Henco multilayer pipes are combined with PVDF or brass press fittings with yellow gas marking. For diesel applications, the sealing material should be HNBR (hydrogenated nitrile rubber). HNBR is a type of rubber that is resistant to high temperatures and petroleum-based oils. This is only the case with gas-marked Henco products.

This is currently being investigated, but we cannot guarantee it yet.

Only Henco standard multilayer pipes and PVDF fittings qualify for this. The Henco brass products may not come into contact with seawater.

Yes, in combination with Henco multilayer pipe and PVDF fittings. The brass threaded fittings must not come into contact with softened water.

Yes, and for fittings this applies to both PVDF and brass fittings. For that application, the correct ratio is 45% glycol and 55% water. The minimum temperature is -10°C.

Our internal threads are always straight gas threads. Marked with G. G stands for ISO 228. In addition, our external threaded fittings are always conical threads. Marked with R and ISO 7/1. R stands for tapered. To have a good seal, a conical thread must always be tapered into a straight thread.

Female threaded fittings have straight threads and only taper should be screwed in to have good sealing. Only when there is a seal such as a flat seal or o-ring can it be done with straight thread.

Couplings with flat seal can only be combined with straight thread.

The 24P-/25P fitting and a jacketed or pre-insulated pipe.

Henco press fittings with a diameter of 14 mm up to 90 mm (and soon 110 mm) must be pressed with the Henco BE-profile. The BE-profile is the same as the TH-profile for diameters up to 26 mm. The TH-profile can therefore also be used to press couplings up to diameter 26 mm. From a diameter of 32 mm onwards, jaws with the BE profile must always be used.

Check which certificates Henco complies with here.

Yes, however mechanical compression using an olive or threaded joints should not be embedded.

The locating collar ensures that the pressing sleeve is correctly positioned in the pressing jaw.

The standard dimension is 153mm, only the 28PV-16031603-1 has a centre distance of 120mm.
