Do you have questions about polycarbonate tubing?
Can polycarbonate tubing be used with conventional gauge glass valve sets?
Yes, as long as you select the correct outside diameter (O.D.) for the given valve set and do not try to use the tubing beyond its safe temperature range
For extra long lengths of polycarbonate tubing, do I need any kind of support?
Yes, tube holders are recommended for extra long lengths because polycarbonate tubing does not have the same inherent rigidity that borosilicate glass does. Contact and ask us for more details.
Is polycarbonate tubing safe to ship?
Yes, polycarbonate is very versatile and is commonly offered as an alternative to ordering tubular sight glass if there is a long distance between Keystone and our customer. Unlike tubular sight glass, polycarbonate tubing does not easily break.
What are the technical limitations of polycarbonate tubing?
Polycarbonate tubing is rated for pressures up to 240 psi at a temperature of 72°. Please ensure that tubing is compatible with the media before placing an order with Keystone.
Additionally, polycarbonate tubing is not suitable for outdoor environments.
