O-Rings
System-matched sealing compounds for water, gas, heating, air and refrigerant-oriented PCC applications.
PCC sealing support covers multiple compound options selected according to service medium, temperature, approval requirements and fitting family, with technical support from LAV.EL. Gomma S.r.l for material coordination.
Support Highlights
- Black EPDM for mainstream water, heating and compressed air-oriented system positions.
- FPM / FKM options where higher chemical or temperature resistance is part of the specification logic.
- Yellow HNBR / dedicated sealing concepts for gas and selected energy or refrigerant-oriented use cases.
- Technical support reference from LAV.EL. Gomma S.r.l helps strengthen material matching and sealing application guidance.
Typical Use
Detail Overview
Application Logic
O-ring selection is described as part of the whole PCC system rather than a standalone spare part. The correct sealing compound depends on the medium, working temperature, pressure range, regulatory requirement and the selected fitting family.
Coordination With PCC Systems
PRESS INOX, PRESS STEEL, PRESS COPPER and PRESS INOX ACR systems may use different sealing materials according to service conditions. Seal selection should therefore follow the selected fitting family and application requirements.
Technical Support
LAV.EL. Gomma S.r.l is referenced as the sealing technology support source for compound know-how, helping extend the completeness of the PCC support offer without weakening PCC front-end branding.

These second-layer cards break the support range into clearer picture-and-copy style groups so visitors can understand the matching logic in a more visual way, similar to the press-fit product families.
EPDM Range
Used for mainstream water, heating and compressed-air services where a widely adopted sealing material is required.
FPM / FKM Range
Used when specification logic points to stronger chemical or temperature resistance and the sealing decision must be coordinated with the selected PCC system family.
HNBR Range
Applied where gas, energy or refrigerant-related sealing logic requires a different compound direction, especially around dedicated PCC gas or ACR discussions.
