Spherical Joint: Ball, Cup & Clip

PISCO® Spherical Joints (Ball & Cup with Clip) are precision-engineered connectors used in laboratory glassware to allow flexible, leak-proof, and secure articulation between glass components. Manufactured from high-quality low expansion borosilicate glass (3.3), these joints provide excellent thermal and chemical resistance, making them ideal for use in distillation units, gas analysis systems, and other modular lab setups.

The spherical design allows for a certain degree of movement and angular adjustment between connected glass parts, reducing the risk of breakage due to thermal expansion or mechanical stress. The accompanying stainless steel or PTFE-coated clip ensures a tight and secure hold during use. Available in multiple standard joint sizes, PISCO® Ball and Socket Joints are compatible with various international systems such as ASTM and ISO.
