The P16 type seal is a multi-component combined piston sealing set, consisting of one pressure ring, one support ring, and one to two V-shaped piston sealing rings. The product supports diversified material configurations, with pressure rings and rubber rings optional in NBR and FKM materials, and support rings available in NBR, FKM and POM. Designed for harsh and severe working conditions, this versatile V-seal assembly is widely adopted for the maintenance and replacement of old hydraulic equipment. It supports single-side pressure sealing and back-to-back double-sided pressure sealing installation, featuring strong adaptability to complex and extreme working scenarios.

• Pressure Ring & Rubber Ring: Optional NBR (Nitrile Butadiene Rubber) and FKM (Fluororubber) materials. NBR features excellent elasticity and cost performance for conventional working conditions; FKM owns outstanding high-temperature resistance, oil resistance and chemical corrosion resistance for harsh environments.
• Support Ring: Available in NBR, FKM and POM materials. POM provides high rigidity and superior anti-extrusion performance; NBR and FKM offer elastic support and good medium adaptability, meeting different pressure and temperature level requirements.

• Adaptable to Harsh and Severe Working Conditions: The multi-layer combined V-type sealing structure has super strong environmental adaptability, capable of stably operating in extreme and harsh hydraulic working environments that ordinary single seals cannot withstand.
• Professional Maintenance Spare Parts for Old Equipment: Optimized for the dimensional and structural characteristics of traditional old hydraulic equipment, it perfectly meets the replacement and maintenance needs of aging equipment, solving the problem of difficult matching of old model seals.
• Diversified Installation Methods: The V-shaped seal set supports single-side pressure bearing sealing for individual piston working conditions. Adopting back-to-back installation, it can be applied to piston sealing systems with pressure on both sides, realizing flexible adaptation to different pressure modes.
• Extreme Working Condition Resistance: The composite structure of pressure ring, support ring and V-shaped seal ring achieves super high pressure resistance and impact resistance, reliably bearing extreme complex working conditions.
• Long Service Life: With reasonable structural stress distribution and wear-resistant and pressure-resistant material collocation, the product has excellent fatigue resistance and durability, maintaining long-term stable operation.
• Customizable Performance Matching: The material combination and assembly quantity can be optimally adjusted according to the actual usage of different equipment to achieve targeted sealing performance and meet personalized working condition requirements.
• Strong Tolerance for Poor Surface Quality: It has low dependence on the surface finish of hydraulic parts, and can maintain stable sealing performance for a certain period even when the equipment surface quality is poor.
• Insensitive to Hydraulic Medium Pollution: The structural design has strong pollution resistance, is not sensitive to slight pollution and impurities in hydraulic oil, and reduces sealing failure caused by medium contamination.
• Structural Characteristics: Due to the particularity of the multi-group composite structure, slight occasional leakage or friction fluctuation may occur under individual special working conditions, which belongs to normal structural design characteristics.

Widely used in injection molding machines, hydraulic presses, marine hydraulic systems, scrap steel shearing machines, metallurgical equipment, special hydraulic cylinders and heavy-duty machinery. It is the preferred sealing solution for maintenance and operation of various heavy-duty and old hydraulic equipment under harsh working conditions.
