Product Description
Building apparatus that seals cleanly without grease starts with a well-made outer joint. These CLEAR-SEAL outer joints give glassblowers a strong, ready-formed female standard taper member to fuse onto flasks, condensers and adapters during repair or custom fabrication, with sizes that match common standard taper apparatus.
This listing is for Wheaton catalog number 758966: CLEAR-SEAL Grease-Free Outer Joints, 14/20 mm, Case of 6. Formed from tubing heavier than standard wall for extra strength, the joints are made of WHEATON 33 low extractable borosilicate glass meeting ASTM E438 Type I, Class A. Their smooth sealing surfaces close without lubricant and resist seizing. Sizes 14/20, 19/22 and 24/40 are available, six per case. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
