Mobile Toilet Seal Ring

The common types and functional characteristics of seal rings used in mobile toilets (toilets) are as follows:

1. Adjustable-distance Eccentric Flange Offset Connector
This type of seal ring is specifically designed for toilet offset. Its core function is to achieve flexible distance adjustments of 2/3/5 centimeters through the eccentric structure made of rubber material, allowing installation without damaging the floor. Its odor-proof principle lies in the tight fit between the seal ring and the drain pipe opening, combined with the elastic deformation ability of the rubber, which effectively blocks the backflow of odors. Typical application scenarios include bathroom layout renovations or corrections of drain pipe position deviations. For example, the model offered by Suqian Haixi Information Technology Co., Ltd., starting at 26 yuan, uses high-density rubber material, has excellent aging resistance, and a service life of over 5 years.

2. Extended Flange Seal Ring
As an upgraded product of traditional flange rings, its structural feature is an increase in the sealing surface length by 20%-30%, enhancing sealing stability by increasing the contact area. Some manufacturers offer free upgrade services, such as adding metal reinforcement rings or silicone lubrication layers, which can reduce the risk of leakage caused by installation errors. This type of seal ring is suitable for high-rise buildings or geological subsidence areas, effectively addressing sealing challenges caused by slight displacement of drain pipes.

3. Universal Odor-proof Flange Seal Ring
This type integrates an automatic one-piece check valve design, achieving one-way drainage through gravity or spring mechanisms. In terms of material, it mostly uses a composite structure of thickened ABS engineering plastic and nitrile rubber, ensuring both structural strength and corrosion resistance. The price range varies widely (5.33-55 yuan), with differences mainly reflected in the precision of the check valve and the thickness of the seal ring. For example, the flagship model from Nan'an Modeman Home Furnishings is equipped with double-layer silicone sealing lips, capable of withstanding extreme temperatures from -20℃ to 80℃, suitable for cold northern regions or underfloor heating environments.

4. Brass Flange Ring
Made primarily of H62 brass, it forms a one-piece structure through precision casting, with advantages such as aging resistance, high-pressure resistance (up to 1.6MPa), and strong versatility. Its sealing principle relies on the hard sealing cooperation between metal and ceramic, suitable for scenarios with significant vertical deviations in drain pipes. It should be noted that brass material is sensitive to acidic cleaners, and long-term use may lead to electrochemical corrosion. It is recommended to install it with neutral sealant.

Purchase Recommendations:

• For offset needs, prioritize eccentric flange offset connectors
• For geologically active areas, recommend extended or brass models
• For high odor-proof requirements, choose universal models with check valves
• For specific parameters, refer to product detail pages on e-commerce platforms or contact manufacturers for installation drawings and load-bearing test reports.
