How to select an SSTM silencer
- Identify the mating port's thread standard: NPT, PT or metric M5.

- Select the required stainless steel grade: 304 or 316.
- Choose a pack of 2, 5 or 10 pieces.
Thread selection questions
Are SSTM NPT1/4 and PT1/4 the same option?
No. NPT1/4 and PT1/4 are listed under different thread standards. Match both the standard and size to the mating port rather than choosing by the shared 1/4 label.
Does M5 mean a 5 mm tube connection?
No. M5 × 0.8 is the listed metric thread specification for this silencer, not a tube outside-diameter option.
What identifies the SSTM design?
SSTM identifies the flat sintered pneumatic silencer in this listing. When replacing a component, check the design as well as the connection thread and material grade.
