Description

Stainless steel fastening from Ø33.7mm to Ø42.4mm pipe - two-piece & for clamping

A connector that not only holds, but also makes an impression. The two-part tube fastening made of high-quality stainless steel V2A is for the precise transition from Ø33.7mm to Ø42.4mm round tubes, ideal for balusters, handrails or stainless steel constructions where stability and design are equally important. The surface is polished, which ensures a silky matt, elegant look and also protects against corrosion. As a result, the component blends in perfectly with modern stainless steel railings and harmonizes visually with polished handrail tubes or posts.

The milled side accommodates the Ø42.4 mm tube precisely. It is fitted with a grub screw that can be used to loosen or readjust the part - practical for maintenance or disassembly. On the straight side is the holder for a Ø33.7 mm tube, which is inserted precisely and fixed securely with the integrated M8x30 threaded screw.

Areas of application

The two-part stainless steel connector is a versatile and technically precise component for the transition connection of pipes with different diameters, ideal for professional use in railing, building and metal constructions. Thanks to the clamp connection with M8x30 screw, installation can be carried out quickly, cleanly and without welding.

  • Railing and handrail construction
    the connecting element is ideal for connecting a filler or cross tube with Ø 33.7 mm to a main post or handrail with Ø 42.4 mm. This allows side elements, intermediate struts or filler rods to be attached with a perfect fit, for example for stair and balcony railings, terrace or balustrade constructions or stainless steel internal handrails
  • Tubular frame and construction technology
    the component is used as a transition connector between pipe sizes in workshops, machine frames or pipe systems. It ensures a stable, backlash-free connection between 33.7 mm and 42.4 mm stainless steel tubes, for example in support and holding frames made of round tube, covers, protective grilles or housings, stainless steel supports, display cases or rack structures
  • Architecture and interior design
    the connecting element also offers a wide range of possibilities in the decorative area, such as for connecting stainless steel pipes in furniture, room dividers or displays, as a stable support connection for modern stainless steel or glass railings, in combination with pipe connectors, glass holders or filler rod holders

Information on product safety:

Warning notices:

  • Keep away from other metals! Stainless steel should never be brought into direct contact with other metals, or in their immediate vicinity, because contact corrosion or cross-contamination can occur. Contact corrosion and cross-contamination can weaken the metals concerned and impair the stainless steel's non-corrosive properties. In the long term, complete material failure cannot be ruled out.
  • Risk of rust! This stainless steel has only a low resistance to chemicals and acids in particular. For this reason, we advise against using it in aggressive environments, as this could damage the corrosion protection and lead to material failure. For example, use near pools, in cities with high levels of air pollution and in places in the immediate vicinity of the sea is not recommended!
  • Follow the care instructions! Please follow the care instructions for the product. If not handled correctly, the stainless steel may lose its non-corroding properties.

Care instructions:

Stainless steel must be cleaned and cared for at regular intervals. If this care is not carried out, the material may lose its stainless properties. You can use commercially available, non-acidic cleaning agents for cleaning. Please also note that the occurrence of occasional flash rust cannot be ruled out. Flash rust should be removed as quickly as possible to avoid any material damage.
