Crowring spanner No. 440S MJ24 for pipe DN16 3/8 inch drive length 49.5 mm - Stahlwille 02211024

Toothed union nuts on pipelines cannot be gripped properly with an open-ended spanner or a socket. The Crowring spanner No. 440S engages the MJ24 nut on the DN16 pipe with straight cylindrical involute toothing to EN 4108 and is slipped over the line from the side. It is driven through its 3/8 inch square drive by a ratchet or torque wrench, with a height of only 9 mm (dimension a).

Benefits

• Straight cylindrical involute toothing for pipe fittings to EN 4108
• Fits nut thread MJ24 and external pipe diameter DN16
• 3/8 inch female square drive for ratchets and torque wrenches
• Compact dimensions: length 49.5 mm, width 39 mm, dimension a 9 mm, weight 56 g
• HPQ high performance steel (High Performance Quality), chrome-plated

Applications

Assembly and maintenance of pipelines with toothed union nuts to EN 4108, for example in aviation maintenance, hydraulics and plant building. Combined with a torque wrench, the fittings can be tightened in a controlled way. If the Crowring spanner is not mounted at a right angle to the lever, the changed effective lever length must be taken into account in the set value.

Standards

Toothing to EN 4108.
