Frequently asked questions

Can Gastite^® be installed within flooring screed?
Absolutely. After the piping is laid, and prior to pouring screed, the entire run of Gastite^® that is to be buried must be examined visually and manually. The installer must closely inspect the jacket over the entire length to check for any damage or voids which could affect corrosion resistance.

If damage is found, it should be repaired by wrapping self-amalgamating jacket repair tape around the damage. Tape wrapping must be done using Gastite^® self-bonding silicone tape.

And remember, while the CSST can be buried, Gastite^® fittings must always be located in an accessible area and therefore must not be buried.

Is there a way to reduce down from a larger sized Gastite^® pipe to a smaller copper one?
Yes. Our copper compression fittings allow for sizing down, for example, with our XR2^™ CC-DN25X22 copper compression fitting it is easy to drop from DN25 down to 22mm copper. For larger sizes, where a compatible copper compression fitting is not available, we recommend joining a male fitting on to a malleable iron reducer. This will then allow for connection between the larger and smaller pipe.

Can Gastite^® CSST be used for a garden firepit?
Gastite^® CSST is a great choice for firepits and gas BBQs. The CSST can be run externally from the propane cylinder and then taken underground before it meets the firepit. The polyethylene jacket has both UV and ozone resistant properties, making it safe for external use. In fact, the jacket will not weather, split or deteriorate when in contact with the elements.

Do I need a collar to seal the ducting to the plasterboard as it passes into an apartment?
We recommend that you use a fire mastic to seal around the duct where required. Where the duct enters through the ceiling, we advise that the edge just passes the ceiling line to ensure that in the event that the sleeve conveys leaking gas, it will not enter the void.

Can Gastite^® be run externally, for example, up the outside of a house?
Gastite’s^® polyethylene jacket is robust and able to withstand the rigours of installation. Thanks to both UV and ozone resistant properties, the jacket will not deteriorate when in contact with the elements.
