BP1: Material: Borosilicate Glass. Type: Tube Spirit Vial Levels. Fluid: Clear. Length(L): 35 mm. Diameter(D): 10 mm. SKU: 185. With Nib (+2mm).. BP2: Sensitivity: 60" / 2mm. Perfect for mechanical tasks. The 60" sensitivity over 2mm detects slopes of 0.291 mm/m, making it ideal for aligning components accurately.. BP3: Borosilicate glass, composed of silica and boron trioxide, resists cracking or breaking under rapid temperature changes due to its low thermal expansion, making it highly durable and reliable.. BP4: The bubble level's sensitivity is measured by the tilt required to move the bubble 2 mm, with lower angles indicating higher sensitivity.. BP5: Easy-to-read borosilicate vials with durable baked ceramic lines for quick accurate leveling. Stress-relieved and filled with fast-setting fluid, these vials meet exacting standards for precision.. || PRODUCT DESCRIPTION SUMMARY: Spirit bubble level vials, made from durable borosilicate glass, feature permanently baked ceramic lines for precise, clear readings. Resistant to thermal stress and filled with stable, low-viscosity liquids, they ensure accuracy in varying conditions. These stress-relieved vials are ideal as replacement parts for spirit levels, custom leveling tools, or precision alignment tasks in construction, machinery, and DIY projects.. || Please see the technical image illustration for size references.
