Changing Glovebox Gloves
Gloves are the most common consumable item in a glove box. We explain when they need to be replaced, what materials and sizes are available, and how to replace them without disrupting the inert gas atmosphere.
The gloves are the most vulnerable part of any glove box: they are subjected to heavy mechanical stress, degrade due to chemicals and UV light, and become brittle over time. A leaky glove allows oxygen and moisture to enter the box—causing the parameters to rise and compromising the work. Replacing them in a timely manner is therefore one of the most important maintenance steps.
How to tell when it’s time for a replacement
- Visible tears, porous or discolored areas, especially on the fingers and in the creases.
- Rising O₂/H₂O levels with no other apparent cause.
- Material fatigue: The glove becomes hard, sticky, or loses its elasticity.
- After contact with chemicals that can damage the material.
What materials and sizes are available?
Glovebox gloves vary in material, size, and port diameter. Common materials include butyl (good gas tightness, chemically resistant), neoprene (durable, good tactile sensitivity), and Hypalon (high chemical resistance). The appropriate material depends on the substances being used. The glove size and port diameter (the opening into which the glove is inserted) are also important—both must fit the system.
Changing Gloves Without Losing Atmosphere
On many systems, gloves can be changed using the double-glove technique: The new glove is placed over the old one at the port so that the box remains closed during the change. As a general rule:
- Have a compatible glove (material, size, port diameter) ready.
- Check the O-rings or clamping rings and the seal at the port.
- Perform the change with slight overpressure if possible to prevent air from entering.
- After the change, check the seal and monitor the box readings.
If you’re unsure or if the replacement needs to be done while maintaining the atmosphere, we’ll be happy to handle it—for any manufacturer and, upon request, as part of your regular maintenance.
Purchasing Gloves
We offer glovebox gloves in various materials and sizes—along with other consumables such as filter cartridges and gaskets. For an overview, visit the Glovebox Accessories & Consumables page. Just let us know the manufacturer, size, and port diameter, and we’ll deliver the right fit.
Changing Gloves: Frequently Asked Questions
How often should Glovebox gloves be replaced?
There is no set interval—the condition of the gloves is what matters. Gloves are visually inspected on an ongoing basis and replaced if they show tears, signs of material fatigue, or rising O₂/H₂O levels. They are replaced more frequently during intensive use.
Which glove material is the right one?
That depends on the chemicals used. Butyl offers good gas tightness, neoprene provides good tactile sensitivity, and Hypalon offers high chemical resistance. We'll advise you based on your specific application.
Can I change gloves without losing the inert gas atmosphere?
Yes, for many systems, this is done using the "double-glove" technique: The new glove is slipped over the old one so that the box remains closed. We can handle the replacement for you upon request.
Gloves for your glove compartment?
Just tell us the manufacturer, size, and port diameter—we'll supply the right gloves and, if you'd like, handle the replacement.
