How do I choose the right rubber gasket for my plumbing?
Selecting the right rubber seal for plumbing is one of the most important design decisions in plumbing, contracting and manufacturing companies. Even a perfectly designed pipe or prefabricated component will not perform its function if the sealing element is not matched to the connection type, diameter, tolerances or operating conditions. This is why it is so important to work with a manufacturer that specialises in the plumbing industry - such as MOL ROMGUM, which has been designing and manufacturing rubber seals for underground infrastructure for more than 40 years.
Why is the choice of gasket so important?
The rubber gasket has more functions than it may appear. It is responsible not only for the tightness of the joints, but also for tolerance compensation, stress absorption, maintaining a stable pipe geometry and resisting soil and water pressure. If the gasket is selected incorrectly, the installation may show leaks during pressure tests, let ground water through and even lead to the formation of a unsealed socket. In extreme cases, this leads to the need to dig up the section and carry out repair work - which generates costs many times higher than the price of a correctly selected gasket.
MOL ROMGUM gasket materials - what to choose?
The most commonly used material in plumbing systems is EPDM, because of its high resistance to moisture, water, ozone, UV radiation and temperature fluctuations. MOL ROMGUM EPDM gaskets remain flexible for many years, which is essential for the long-term operation of gravity and pressure sewers.
The second essential material is NBR, used in installations where petroleum-based substances may occur - e.g. in industry or systems exposed to oil. SBR and other MOL ROMGUM rubber compounds are used primarily in precast concrete construction, where compression resistance and large tolerance ranges are important.
How do I choose a plumbing gasket correctly?
It is crucial to pay attention to the following elements:
1. pipe diameter and tolerances
Even minimal dimensional deviations can cause installation problems. MOL ROMGUM manufactures gaskets ideally suited to specific pipe systems - both PVC/PP/PE and concrete pipes.
2. connection type
- socket connections,
- flat connections,
- connections for concrete pipes,
- hybrid connections.
Each of these types requires a different type of gasket, appropriate mounting tabs and geometry.
3 Operating conditions
Depth of placement, soil type, traffic loads, temperature fluctuations or water pressure all affect the choice of rubber compound.
4 Standards and design requirements
MOL ROMGUM gaskets meet the quality requirements used in plumbing systems, ensuring dimensional repeatability and mechanical stability.
Why do B2B companies choose MOL ROMGUM?
It is not just a manufacturer, but a technology partner. The company offers:
- technical advice on the selection of seals,
- production of gaskets tailored to specific diameters and geometries,
- long-life rubber compounds,
- stable quality confirmed by production control.
Gaskets from MOL ROMGUM
The right choice of gasket is not about saving „on a component”, but about saving on the entire investment. MOL ROMGUM supplies rubber gaskets specifically designed for reliable, long-lasting plumbing installations.
