We export PE electrofusion fittings worldwide. Low pressure couplers are individually polybagged, cartoned and palletized for safe sea freight.
We stand behind the quality of our electrofusion fittings. Our commitment doesn't end at delivery — we provide comprehensive technical support for your PE pipeline project.
It joins two PE pipes of the same diameter with a fully welded electrofusion joint for low pressure water systems. Typical applications include water distribution, gravity sewer, irrigation and mining networks from DN315 to DN400.
The coupler is specifically developed and tested for thin-walled PE pipes from SDR 17 to SDR 26, which are commonly used in low pressure water applications.
The coupler is rated water PN10 (dependent on the PE pipe welded and local pipeline pressure regulations). It is suitable for water, wastewater, irrigation and mining applications.
Three references are available: DN315 (CBKHFM315LP), DN355 (CBKHFM355LP) and DN400 (CBKHFM400LP).
The standard MOQ is 100 pieces per size, but we are flexible for trial orders. Smaller sample quantities are available for evaluation. Contact us with your required sizes and quantity for a tailored quote.
