The titanium internal tooth gasket launched by Baoji Qinhao Company is not only a gasket, but also an active anti-loosening and sealing system combining aerospace-grade titanium alloy materials and precision internal tooth locking structure by Qinhao, which is a reliable line of defense to protect the long-lasting and stable of key connections.
Core advantages

Aerospace-grade titanium alloy material
Excellent corrosion resistance: It is not afraid of acid and alkali environments, especially suitable for harsh working conditions such as marine engineering and chemical equipment, and its service life is greatly extended.
High specific strength: The strength is comparable to that of high-grade alloy steel, but the weight is about 40% lighter, making it the perfect choice for lightweight and highly reliable fastening of equipment.
Wide temperature range stability: It can still maintain excellent mechanical properties in ultra-low temperature cryogenic or high-temperature environments, meeting extreme needs such as aerospace.
Safe and clean: It has excellent biocompatibility, non-toxic and non-magnetic, and can be directly used in high-standard fields such as medical devices and food processing.
Precision internal tooth locking structure
Qin Hao subverts the traditional flat washer or external tooth washer design, and innovatively arranges the precision tooth shape on the edge of the inner diameter to form an efficient locking system:
Active bite anti-loosening: When tightening, the tip of the inner tooth is precisely embedded in the connection surface, forming a microscopic gear meshing effect that mechanically resists lateral and longitudinal displacement.
Dynamic Vibration Absorption: The unique toothed structure effectively disperses and absorbs high-frequency vibration energy, converting damaging dynamic shocks into enhanced static bite force.
Multiple sealing lines: The internal teeth form a continuous and precise ring contact line, which can effectively block the leakage of oil, water, gas and other media when sealing is required

Key application areas
With the dual advantages of titanium alloy and internal tooth structure, Baoji Qinhao Titanium Internal Tooth Washer has become the first choice for improving equipment reliability in the following high-demand areas:
Power and drivetrain: automobile engines, turbochargers, diesel units. Effectively resist high-frequency vibration and prevent oil leakage, cylinder head deformation and other faults caused by loose bolts.
Fluid Handling & Chemical Equipment: Pumps, Valves, Pipeline Flanges, Reactors. While ensuring tightening, it provides a reliable auxiliary seal to prevent hazardous media leakage.
Aerospace and defense military industry: aircraft structural parts, spacecraft components, missile shells. It meets the fastening needs of lightweight, high strength, high reliability and extreme environments.
Heavy and construction machinery: excavators, mining equipment, large lifting machinery. Withstand heavy loads and shock loads to prevent the failure of critical connections due to loosening.
High-end precision and medical equipment: CNC machine tool spindles, medical imaging equipment (such as CT, MRI), high-end dental chairs. Ensure long-term stable accuracy and silent and reliable operation.
Marine and Ship Engineering: Marine engines, propeller shafts, deep-sea exploration equipment. Perfectly resists seawater corrosion and provides a long-lasting, maintenance-free fastening solution.
