WALFORM
Seals
Replacement soft seals in FKM 90 for compatible WALFORM-type tube fitting connections. Select the seal by tube outside diameter and L or S series.
DIMENSIONS
L and S series
Use the tube outside diameter (dN) and series to find the STEMA reference. Full fitting geometry, l1/l2, S2 and system PN are available in the Technical Datasheet.

Note: The same STEMA reference (e.g. WF 06L/S) may appear in both the L and S series even though the fitting threads differ. The reference identifies the seal; the thread dimension identifies the fitting. Always verify tube diameter and series when selecting. PN in the datasheet is the system reference pressure and must not be interpreted as an independent pressure rating for the elastomer seal.
