O-ring Joints, Borosilicate

Item #: CG-124

Normal Availability: 1-3 business days

Product Description

These borosilicate glass joints have an O-ring groove to accept the listed O-ring size and provide a grease-free vacuum seal when used with CG-150 clamps. Each joint is supplied with a Viton O-ring of the listed size. Clamps and additional O-rings are sold separately. Available in #5, #7, #9, #12, #15, #20, #25, #30, #35, #40, #50, and #75 sizes.

The interior diameter of the tubing matches the size - for example, a #15 O-ring joint has a 15 mm inner diameter.  For a discussion of O-ring joints, see the Joints entry in the Glassware Gallery.

For stainless steel O-ring joint clamps see item # CG-150.

A limited size range of quartz O-ring joints is available by special order. Contact us for pricing and availability.
