Borosilicate Glass Y-Joint Adapter | 24/40

The Borosilicate Glass Y-Joint 24/40 is a Y-shaped laboratory connecting adapter with two outer 24/40 standard-taper joints and one inner 24/40 joint. It can be used to create a branching connection between compatible laboratory glass components.

All three connections use the nominal 24/40 standard-taper size, making the adapter useful when a laboratory setup requires one connection to branch into two compatible paths. Standard joint sizing improves interchangeability, but actual fit should still be checked before operation because glass condition and manufacturing tolerances can vary.

This 24/40 Y-joint adapter is made from borosilicate glass. The current product information does not establish a specific thermal-shock limit, maximum operating temperature, pressure or vacuum rating, or universal chemical-resistance specification.

Inspect the adapter before every use for chips, cracks, star fractures, damaged joint surfaces, or contamination. Support connected glassware independently rather than allowing the Y-joint to carry excessive weight or mechanical stress. Use appropriate Keck clips or clamps where suitable for the apparatus.

For heated, vacuum, pressure, or hazardous-chemical applications, evaluate the complete assembly and use appropriate shielding and PPE. Browse additional borosilicate laboratory glassware for compatible components.

Frequently Asked Questions

What connections does the Y-joint have?
The listing specifies two outer 24/40 standard-taper joints and one inner 24/40 joint.

Will every 24/40 component connect to it?
Match the joint orientation as well as the size, and check the actual fit. Components need complementary mating joints.

Can it support other glassware without clamps?
Support connected components independently so their weight does not place excessive stress on the adapter.
