The coaxial sliding sleeve is a separate component in the double-containment fitting range. Match its outside diameter, inside diameter and axial length to the approved tube assembly rather than relying on nominal size alone. The white-background cutaway is illustrative; the catalog dimensions control selection.
Technical parameters
| Component | Coaxial sliding sleeve |
|---|---|
| Nominal sizes | 1/4–2 in in the catalog |
| 1/2 in example OD | 22.23 mm |
| 1/2 in example ID | 19.25 mm |
| 1/2 in example length A | 101.6 mm |
| Material / finish | Confirm grade and finish against the assembly specification |
Catalog dimensions are selection references. Confirm the exact grade, finish, geometry and inspection documents against the approved order drawing.
Application and selection
Use the sleeve only as part of a compatible coaxial tube detail. Installation sequence, weld locations and the outer containment path need to be reviewed together before procurement.
What to send for a quotation
Provide nominal size, mating tube OD/ID, assembly drawing, material and surface-finish requirements, and quantity. Contact LGF with your requirements.
