PEX pipes are manufactured from homogeneous PE-Xa in the highest quality in our Swedish production facility. Pipes suitable for portable water. The pipes are equipped with an oxygen barrier, which means that they can also be used in heating systems without the risk of oxygenation of the water. The pipes are available as Pipe-in-Pipe (PiP) with gray conduit pipe or with extra-insulated conduit pipes (PiP Extra) alternatively as bare pipe. The PEX pipes are available in dim. 16, 20 and 25 mm, and is delivered on rolls up to 200 meters.
PAL pipes have an inner layer of PE-RT, an intermediate layer of aluminum and a surface layer of PE-RT. Pipes suitable for portable water. Thanks to the intermediate layer of aluminum, the pipes are diffusion-tight. They are also straight and stiff, almost like a metal pipe, although they weigh much less and are thus easier to handle. They are perfect for visible installations and vertical or horizontal main risers. The pipes are available in dimensions 16-75 mm in straight lengths and in coils up to dimension 40 mm.
A large proportion of the PressPex range is now lead-free, and thus better both for the environment and those who use the systems. The LK Universal Eco product series is manufactured from dezincification resistant lead-free brass and comprises press fittings, manifolds and wall boxes used in plumbing installations. The products have been assigned type approval number TG1550 issued by KIWA Sweden.
The new angle wall bracket Grip V2 is intended for pipe exits, through walls and floors and has a compact construction dimension where a minimum of only 55 mm free space is required. Use LK Angle Wall Bracket Grip V2 with a 25 mm conduit pipe and Universal pipe. Grip V2 can be attached to the LK Angle Wall Support, a cross studs / wood stud.
LK Ball valve high neck M-thread & LK PressPex Valve fitting for quick mounting of stem valves. Simplifies and speeds up installation of PAL/multilayer pipes during stem laying as no sealant is needed. The fitting has a loose nut with an M thread and a coupling seat with a metallic seal. The fittings are made from dezincification-resistant, lead-free brass.
