RUBBERSEAL PRO 110 —
EPDM rubber gasket for water, outdoor and elastic sealing
Fibre gaskets seal by controlled compression. RUBBERSEAL PRO 110 seals by elastic recovery and EPDM compatibility. It is not a higher-duty fibre gasket and it is not a repair for damaged faces. It is the rubber choice for water, outdoor exposure, UV, ozone and fittings where lower bolt load or minor surface variation matters more than high-temperature rigidity.
Selection rule: Use RUBBERSEAL when the joint needs EPDM compatibility, elastic recovery or outdoor resistance.
Use this when: water, outdoor, garden, HVAC and lower bolt-load connections where EPDM compatibility and elastic recovery are useful.
Do not use this when: do not use it for oils, fuels, hydrocarbons, gas service, steam or temperatures above the EPDM grade envelope.
Move to the next material when: the medium needs oil or fuel resistance, the duty needs higher continuous temperature, or the application requires gas or industrial approvals.
What it is
RUBBERSEAL PRO 110
RUBBERSEAL PRO 110 is an elastomeric flat gasket manufactured from EPDM rubber. It is the rubber gasket in the Kinetics Line system — distinct from all five fibre composite series in both material behaviour and the service conditions it is suited for.
Where fibre gaskets seal by controlled compression of a rigid matrix against the flange face, EPDM seals by elastic deformation and recovery. The elastomer can tolerate minor surface marks and small variations better than a stiffer fibre gasket, especially where bolt load is limited. It is not a substitute for correcting a damaged face; if the face itself is the main problem, the selection moves toward a high-compressibility material such as FLEXSEAL.
The temperature ceiling is lower than the fibre composite series — continuous service to +110°C, maximum pressure 10 bar. This is not a limitation in the context of its intended service range. Potable water, outdoor fittings, garden irrigation, HVAC connections and standard domestic heating all operate well within this envelope.
This article refers to the standard EPDM grade. Where food-contact or regulated-use compliance is required, the specific grade and approval status should be verified against the actual grade specification before specification. FDA-compliant grades may be available within the wider EPDM range — confirm before specifying for regulated applications.
Why rubber — not fibre — for these applications
The Kinetics Line system contains five fibre composite gasket series. Each is engineered for controlled compression against a clean, machined flange face under defined bolt load. They are usually the correct choice for those conditions. They are not suitable for every sealing situation.
Rubber gaskets behave differently. The key differences in service:
Where RUBBERSEAL PRO 110 is used
Water supply & plumbing
Hot and cold water connections, BSP threaded fittings, compression fittings. Flexible sealing on common threaded water connections where surface conformity is more relevant than the rigidity of a fibre gasket.
Outdoor & garden
Outdoor tap fittings, garden hose connections, irrigation manifolds. EPDM resists UV, ozone and outdoor weathering over service life — where standard rubber compounds tend to degrade.
HVAC & building services
General water connections in HVAC systems, fan coil units, air handling equipment. Low bolt load and flexible sealing for non-critical connections within the temperature range.
Heating — low temperature circuits
Radiator valve connections, flexible hose fittings and low-temperature heating circuits operating within +110°C. For high-temperature heating above 110°C, the specification moves to GREENSEAL PRO 180 or BLUESEAL ULTRA 350.
Industrial — general water and air
Water and air service where the fitting needs elastic recovery and EPDM compatibility. Minor surface marks may be tolerated, but damaged faces still need proper correction or a different gasket strategy.
Regulated applications — verify grade
FDA-compliant grades may be available within the EPDM range for food-contact and sanitary applications. Compliance should be verified against the specific grade specification before specifying for regulated use.
When to use it — and when not to
Where RUBBERSEAL makes sense
- Water supply, potable water, hot and cold plumbing
- Outdoor fittings — UV, ozone and weathering resistance needed
- Garden irrigation and outdoor water connections
- HVAC connections within the operating range
- Low bolt load fittings where conformity matters more than rigidity
- Standard heating circuits operating below +110°C
- Applications with minor surface marks or limited bolt load, not damaged-face repair
When RUBBERSEAL is not the answer
- Gas service — specification moves to a DVGW-approved fibre series such as BLUESEAL ULTRA 350
- Oils, fuels, aliphatic hydrocarbons or mineral oils — EPDM is not suitable for hydrocarbon contact
- Steam or water above +110°C — specify a higher-temperature fibre series
- Chemical service — assess the specific medium against EPDM compatibility before specifying
- High-pressure industrial flanges above 10 bar
Not suitable for: oils, fuels, aliphatic hydrocarbons, mineral oils or chlorinated solvents. EPDM is not chemically resistant to hydrocarbons. For oil and fuel sealing, NBR is the usual starting point. For gas service, the specification typically moves to an approved fibre-based series — BLUESEAL ULTRA 350 carries DVGW, subject to the actual approval requirement. For steam or water above +110°C, specify GREENSEAL PRO 180, BLUESEAL ULTRA 350 or GRAPHITESEAL ULTRA 350.
Temperature range in context
The +110°C continuous rating covers the operational range of most domestic and light commercial plumbing and heating applications:
- Domestic hot water: typically 60–65°C at cylinder, lower at point of use
- Underfloor heating flow: typically 35–55°C
- Standard central heating flow: typically 70–80°C
- Pressurised heating systems: up to approximately 90°C flow temperature in most installations
- Garden irrigation and outdoor water: ambient to around 20°C typically
For any service above +110°C continuous — including steam — the fibre composite series should be assessed. The rubber gasket is not rated for that condition.

RUBBERSEAL PRO 110 is the rubber gasket in the Kinetics Line system — for water, outdoor and UV-exposed service where EPDM compatibility and elastic recovery fit the condition better than a rigid fibre composite.
EPDM is usually the first material assessed for potable water, garden fittings, outdoor installations and HVAC connections within its temperature and pressure range. Where the service runs above +110°C, involves oils, fuels or gas, or requires a specific approval framework, the fibre composite series cover those conditions. Each fits a different service envelope and should be selected against actual operating conditions.
