gas sample bags

gas sample bag connectors

Connectors are inserted into the gas sample bag in such a way that only fluoroplastic material can come into contact with the gas sample.


We stock a range of standard PTFE connectors, and for less sensitive applications we also offer a dual use Polypropylene connector.

Find our range of PTFE and Polypropylene gas sample bag connectors below.

More than one connector can be applied to each gas sample bag, and the orientation of these can be tailored to our customers' needs and equipment restrictions.

For larger multiple use gas bags, it's recommended that an internal manifold of FEP scavenger pipes is added to the bag to ensure complete evacuation of gases before re-using the bag.

Should you have bespoke connectors for specific testing equipment, these can also be applied to new bag outers.
