Water & Sanitary Sealing Applications
Pumps and valves
Custom seals for water pumps and flushing systems
Application: Pumps and valves for water and wastewater flow
Seals play a crucial role in valves and pumps ensuring that water is available when and where needed, at the same time guaranteeing that no leakage occurs or excess water is wasted.
Requirements
- Parts fit existing equipment/standard specification requirements
- Excellent chlorine resistance
- Meet multiple global standards
- Long life
- Cost-effective performance
Solution
Rotary Seals, Diaphragms, Custom Molded Parts
Our engineers work with our customers to design, test and identify a sealing solution which meets expectations, thereby minimizing downtime and improving maintenance cycles.
Water Filtration
Materials to comply with global standards
Application: Water filter for commercial and residential water treatment systems
Requirements:
- Materials must meet global standards, including NSF 61, KTW, W270, WRAS and ACS
- Material resistance to chlorine and chloramine
- Cost-effective performance

Water fixtures
Custom sealing solutions for your application
Application: Water fixtures
Within a faucet or showerhead, there are several sealing components. Seals are used to regulate the flow of water, to mix hot and cold waters and also to control the flow of water coming out.
Requirements:
- High reliability
- High-precision components
- Compliance with country specific potable water standards e.g. FDA, , NSF, KTW, WRAS, ACS
Solution
Depending on your specific application needs, Trelleborg Sealing Solutions offers a range of products:
- O-Rings
- LSR Custom molded parts: our flashless molding capabilities ensure a high level of quality and consistency
- Two-component parts: designed with the customer, two-component parts are leak-proof as they are fully bonded and ease the assembly, production and service processes
- Customer-specific solutions
Water Heater
Optimum fit and long service life are crucial
Application: Water Heater
Requirements:
- Tight fit to ensure no leakage
- Low force
- Long service life
- Single material with wide tolerance range
Solution
O-Rings and Custom Molded Parts
Our water heater sealing solutions are developed with intense in-house testing and engineering with the aid of FEA to meet all our customers’ requirements and relevant standards.
Water irrigation
Extending seal life with optimized materials and design
Application: Water irrigation for domestic and professional use
Sealing solutions for water irrigation applications aim to conserve and regulate the flow of water in low-flow valves.
Requirements:
