Connector for pipe 42,4 x 2mm, Satin

The Strofix connector for pipe 42,4 × 2mm, Satin is a stainless-steel inline coupler for Ø42.4 × 2 mm round railing tube, available in AISI 304 or AISI 316. It joins two tube sections in a straight line and has a 4 mm height. Satin finish (a polished version is also available). Attached using adhesive (elements for pasting included).

The fitting is an internal sleeve that bridges the joint between two round tube ends meeting in a straight line. The ultra-thin 4 mm profile makes the coupler nearly invisible once installed — the external surface shows only a minimal seam between the two tube sections. It is used wherever a continuous straight run of Ø42.4 mm round tube railing or handrail exceeds the available tube length and must be extended with a joint. The fitting slides into the bore of both tube ends and is secured with adhesive, creating a rigid, straight connection. The AISI 316 grade option suits coastal or high-humidity installations.

Use cases:

• Joining two Ø42.4 mm round tube sections in a straight line
• Extending handrail or top-rail runs beyond a single tube length
• Creating a continuous straight round tube railing without visible joints
• Splicing cut tube sections to reach a precise overall length
• Marine-grade AISI 316 straight tube joint for coastal installations

FAQ

What tube does this fitting fit?

Ø42.4 × 2 mm round railing tube.

What is the fitting height?

4 mm (H = 4 mm). The ultra-thin profile makes the coupler nearly invisible once installed.

Which finish and grade options are available?

Satin in AISI 304 or AISI 316. A polished version is also available.

Is this a straight or angled connector?

It is a straight inline connector, joining two tubes in a continuous straight line at 180°. For angled connections, use the adjustable flush elbows or cross angles in the Elbows, Connectors category.

How is the fitting attached?

It slides into both tube ends and is secured using adhesive (pasting). The Strofix anaerobic glue (50 mL) is the recommended adhesive.

About Elbows & Connectors

Elbows and connectors are stainless-steel joint fittings that link two sections of handrail or railing tube at a change of direction, creating a continuous, seamless-looking rail line around corners, up staircases and across straight joints. Flush elbows and angles slip over the tube ends and produce a smooth, weld-free joint on the visible surface; welding variants are permanently fused for a rigid connection.

Strofix supplies 15 elbow and connector products for Ø42.4 mm round pipe and 40×40 mm flat square tube, including fixed 90° flush angles, adjustable flush elbows (with one variant covering 0–70°), cross flush angles, tee ("T") connectors, tee corner connectors, inline fittings and welding flush angles — all in AISI 304 stainless steel with a satin finish, with AISI 316 and polished options on selected variants.

The correct fitting depends on tube profile, the angle of the direction change, the number of tube arms meeting at the joint and whether a screwable or welded connection is required.
