How to order spares
Always order spares by using the description given in the column headed 'Available spares' and state the
size, model number and capsule reference.
Example: 1 - Capsule and seat assembly for a Spirax Sarco ½" BPT13S balanced pressure thermostatic
steam trap.
Note: If a non-standard fill capsule has been fitted then the name-plate on the cap is marked with the letters
'NTS' or 'SUB'. The near-to-steam (NTS) capsule can be used, for example, on hospital sterilisers and wet
steaming ovens. Sub-cooled-capsules (SUB) can be used, for example, on vacuum return systems. For
further details on capsule fill and operation see Section 2.1. Capsule type should be specified on the order
otherwise a standard version will be supplied. Older models may be marked slightly differently. Possible
markings are 'G', or 'F'. 'G' is equivalient to 'NTS' and 'F' is equivalent to 'SUB'.
