Material Analysis
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
Main Body
Made of food - grade PP material, it features moisture resistance, corrosion resistance to toilet cleaning agents, and good toughness. It will not become brittle or deform even after long - term exposure to bathroom moisture.
01
Wear - Resistant Components
Key friction parts use reinforced PA (nylon) material, which has high hardness and low friction coefficient, ensuring smooth rotation without jamming after tens of thousands of uses.
02
Sealing Accessories
The sealing ring is made of food - grade silicone, with excellent elasticity and aging resistance, effectively preventing water vapor and dirt from entering the internal structure.
03
Structural Design Highlights

Precision Slow Descent System
The built - in damping core adopts a multi - stage oil circuit design, enabling smooth slow descent starting from 70°, and the closing noise is ≤30dB, avoiding harsh slamming sounds.
Anti - Detachment Structure
The connection between the hinge and the toilet seat uses a double - card slot + limit buckle design, which can withstand a pulling force of ≥80N without falling off, ensuring safe use.

Self - Lubricating Design
The rotating shaft contact surface is designed with micro - convex self - lubricating points, which can form a thin lubricating layer during rotation, reducing maintenance needs and extending service life.
Installation and Adaptation

Tool - Free Installation
Comes with dedicated mounting screws and gaskets. Just align the hinge with the toilet seat's mounting holes and tighten the screws; the whole process takes only 3 - 5 minutes.

Wide Compatibility
Suitable for PP toilet seats with a mounting hole spacing of 40 - 60mm (with small - range adjustability), compatible with most mainstream PP toilet seat models on the market.

Easy Disassembly
Adopts a quick - release design. Press the side unlocking buckle to quickly remove the hinge for cleaning or replacement without damaging the toilet seat.
Application Scenarios
Specially designed for PP material toilet seats, it is widely used in:
Scenario 01
Household bathrooms (especially suitable for families with the elderly, children, or those pursuing a quiet environment).
Scenario 02
Hotel/motel bathrooms (meeting the needs of high - frequency use and durability).
Scenario 03
Public restrooms in office buildings, shopping malls, etc. (easy to install, maintain, and durable).

Common Problem
Is the B108 hinge compatible with all PP toilet seats?
It fits most PP toilet seats with a mounting hole spacing of 40 - 60mm. We recommend checking your toilet seat's hole spacing before purchase.
How to maintain the B108 hinge?
The hinge has a self - lubricating structure, so no additional lubrication is needed under normal conditions. Just wipe off surface dirt with a damp cloth regularly.
What if the hinge becomes loose after long - term use?
You can re - tighten the mounting screws. If the problem persists, contact our after - sales team for wearing parts replacement.
Are the materials safe and eco - friendly?
All materials are food - grade and meet RoHS environmental standards, safe and non - toxic, and will not release harmful substances in the bathroom environment.
