3.Working Principle
The built-in stainless steel spring generates continuous radial pre-tightening force to push the glass fiber filled PTFE sealing lip closely against the mating surface. System pressure further enhances contact tightness to form effective static and dynamic sealing. Glass fiber filler improves the rigidity and anti-extrusion performance of PTFE, resisting deformation under heavy load and friction wear during operation. The spring automatically makes up for component wear, clearance deviation and thermal expansion, maintaining long-term leak-free sealing under complex motion and high-load conditions.
4.Product Details
Material: High-strength glass fiber filled modified PTFE + corrosion-resistant stainless steel energized spring. Manufactured strictly in accordance with international standard seal groove dimensions. Each batch is tested for wear resistance, compression creep, strength and medium compatibility. Fully compliant with industrial environmental and safety standards. Adopts independent moisture-proof and dust-proof packaging with carton outer packing for storage and bulk delivery.
5.Application Range
Widely used in engineering machinery, heavy-duty hydraulic systems, metallurgical equipment, mining machinery, chemical fluid devices and high-load automation cylinders. Perfect for high pressure, heavy load, abrasive medium, frequent reciprocating and rotating sealing occasions.
6.FAQ
A1: It greatly improves structural strength, anti-creep, anti-extrusion and wear resistance, suitable for heavy-load harsh conditions where pure PTFE is easy to deform.
Q2: Is it suitable for heavy pressure and frequent movement?
A2: Yes, fiber reinforced structure can bear heavy load and frequent cyclic movement with stable durability.
Q3: Can it be used in abrasive and corrosive media?
A3: It retains excellent chemical corrosion resistance and owns better anti-abrasion ability for particle-containing media.
Q4: Will it deform under long-term high pressure?
A4: Glass fiber reinforcement effectively restrains creep and extrusion deformation, keeping stable shape and sealing performance.
Q5: Can custom sizes and fiber content formulas be made?
A5: We support custom section sizes, glass fiber proportion and special spring types according to actual working conditions.
