This part, previously assembled using a combination of resin and machined components, has been integrally formed using the reverse drawing process.

The conventional product (resin + machined parts) had issues with airtightness, which were resolved by integrating the parts into a single piece. Additionally, this reduced the assembly workload.

Approximate dimensions: Outer drawing φ18.2mm, inner drawing φ9.9mm, total length 19mm.
