Generally a sealing compound is used on threaded taper fittings. The "compound" can be a liquid/paste or a suitable (gas) PTFE tape. So if the restrictor tube includes a BSP taper fitting then a sealing compound is required.
(Note that gas fire pipework can be done using just compression fittings, and while one can use lubricating / sealing compounds on these, its not required).
Gas grade PTFE tape (similar to that used on water fittings but thicker) is the most common sealing material[1]. Alternatively a compound like Jet-lube V-2 Plus paste would be an example of another typical product.
