Spherical Ball Joint
Product Code : EL-GJ-10257
Lab Glassware Manufacturer is a leading India-based Spherical Ball Joint manufacturer, supplier and exporter, headquartered in Ambala, Haryana, and serving laboratory glassware buyers since 1982. This spherical joint is exported to institutional and industrial buyers across Greece, Cyprus and Turkey, supporting laboratory procurement throughout the Aegean Basin.
Quick Answer: A Spherical Ball Joint is the ball half of a spherical ground-glass joint pair, which mates with a matching spherical cup joint to allow a wider range of angular movement between connected glassware than a standard taper joint – useful in multi-directional vacuum or gas-line laboratory assemblies where components are not perfectly aligned. Lab Glassware Manufacturer finishes each joint with a smooth ground surface to reduce leakage risk, and leaves sockets unprinted to avoid print charring under heat.

Pairing With a Spherical Cup Joint
This ball joint mates with a Spherical Cup Joint of the matching size code to form a complete, angularly flexible connection. Unlike a standard cone-and-socket taper joint, which holds its two connected components in a fixed, straight-line alignment, a spherical ball-and-cup pair permits the connected glassware to pivot within a limited range, which is useful when linking components on a multi-directional vacuum manifold or gas line where perfect alignment cannot be guaranteed. Lab Glassware Manufacturer supplies the ball and cup halves separately so buyers can order the exact quantities their assembly requires.
Frequently Asked Questions
What is a Spherical Ball Joint used for?
It is the ball half of a spherical ground-glass joint pair, mating with a matching cup joint to allow angular movement between connected glassware components in multi-directional vacuum or gas-line assemblies.
Why is the socket left unprinted?
Lab Glassware Manufacturer leaves sockets unprinted to avoid the printed size marking charring under heat during laboratory use.
How does this differ from a standard cone-and-socket joint?
A standard taper joint holds two connected components in a fixed, straight-line alignment, while a spherical ball-and-cup pair permits limited pivoting movement between the two connected pieces.
Does Lab Glassware Manufacturer export Spherical Ball Joints to the Eastern Mediterranean?
Yes, Lab Glassware Manufacturer, based in Ambala, Haryana, India and manufacturing laboratory glassware since 1982, exports Spherical Ball Joints to institutional and industrial buyers in Greece, Cyprus, Turkey and other Aegean Basin markets.
