Trademark and aftermarket notice: Sondex names are used to identify existing equipment for compatible replacement enquiries. They do not imply original manufacturer status, endorsement, authorization or guaranteed interchangeability.

Technical Reference Data

Sondex Gasket HC / VC Reference Dimensions

The following HC and VC values have been transcribed from the supplied Sondex reference list. The stated unit is millimetres.

Dimensional data policy: HC and VC are identified in mm, but the supplied text does not explain their measurement datum points or tolerances. Values must be checked against the original drawing before production or final part matching.

Important: Models with identical HC / VC reference values may still have different plate grooves, port seals or attachment arrangements. Dimensions alone cannot confirm gasket interchangeability. Missing figures have not been estimated.

Sondex Gasket Retention Systems

Glue-On, Hang-On and Sonderlock Gaskets

Retention design is a critical selection factor for Sondex replacement gaskets. The new gasket must be compatible with the existing plate's attachment features.

BONDED RETENTION

Glue-On Gaskets

Bonded gaskets are secured using a suitable adhesive. Installation requires correct surface preparation, adhesive selection and curing procedures.

MECHANICAL RETENTION

Hang-On Gaskets

Mechanical fixing features retain the gasket on the corresponding plate. The tabs and retention points must match.

SONDEX-SPECIFIC REFERENCE

Sonderlock Gaskets

Sonderlock designs require the correct locking profile and matching plate features. A general glue-on or hang-on gasket must not be treated as interchangeable.

Parallel and diagonal flow: The supplied product information mentions these flow arrangements. Verify the correct port-sealing pattern and plate-pack design before ordering replacement gaskets.

Material Compatibility

Sondex Gasket Materials: EPDM, NBR, HNBR and FKM

The supplied technical reference lists NBRB, NBRP, HNBR, EPDM, HT EPDM and Viton A/B/G. The exact compound should be selected according to the operating medium and service conditions.

EPDM FAMILY

EPDM / HT EPDM

Considered for selected compatible water-based duties. Temperature and chemical limits depend on the compound grade.

NITRILE FAMILY

NBRB / NBRP / HNBR

Nitrile-based references for selected process duties. Verify the fluid, operating temperature and cleaning conditions.

FLUOROELASTOMER

FKM / Viton Grades

The supplied range includes Viton A, B and G designations. Exact grade compatibility and availability require review.

Specification verification: The legacy reference mentions a four-hour post-cure at 160°C, ISO9001-2000 and a one-year warranty. These should not be treated as universal or currently verified specifications. Confirm processing conditions, valid certification and commercial terms for each specific order.
