Forever Seals FEP+FKM composite O-ring adopts double-layer composite structure with outer FEP wrapping layer and inner FKM rubber core. It perfectly combines the excellent corrosion resistance of FEP material and outstanding elasticity and high temperature resistance of FKM. The integrated forming structure maintains stable sealing performance under complex medium and fluctuating temperature conditions, suitable for precise sealing protection of various industrial precision equipment.
Forever Seals 3912473 NBR O-ring is a standard circular sealing part perfectly matched with Cummins engine equipment. Made of high-quality nitrile rubber material, it boasts stable physical property and reliable sealing capacity. The compact ring structure can fit tightly into installation grooves, effectively blocking oil, gas and liquid medium leakage, and steadily serve engine systems under conventional operating pressure and temperature.
These seals feature excellent ultra-low temperature resistance, low shrinkage, methane permeation resistance, and flame retardant & explosion-proof performance
TCV type pressure-resistant skeleton oil seal is specially designed for medium and low pressure, rotating and oil-lubricated working conditions.
Forever Seals PTFE-Glass Vee Packing is a precision-machined, stacked V-shaped sealing solution crafted from glass fiber filled polytetrafluoroethylene (PTFE), engineered for demanding applications requiring exceptional chemical resistance and low-friction performance. The glass fiber reinforcement enhances mechanical strength and wear resistance, while the PTFE matrix provides broad compatibility with corrosive media and self-lubricating properties. This combination delivers reliable, maintenance-free sealing in reciprocating and rotary equipment, even under extreme chemical and thermal conditions.
Bakelite handle ball (also known as phenolic handle ball) is a thermosetting plastic operating part based on phenolic plastic (PF). Its core advantages are heat resistance, insulation, oil resistance and wear resistance, which is widely used in machine tools, valves, high-temperature equipment and electrical tools.
Forever Seals SA-Type FKM oil seal features a rugged metal outer casing paired with a high-performance fluororubber (FKM) inner sealing lip, engineered to deliver reliable oil retention in demanding high-temperature, high-pressure environments. The robust metal shell provides structural rigidity and press-fit stability, while the FKM elastomer offers exceptional resistance to heat, oil and chemical degradation. This combination ensures long-term leak prevention in heavy-duty industrial and automotive equipment, even under continuous thermal and mechanical stress.
Blue glass modified PTFE, anti-creep, wear-resistant and dimensionally stable
Forever Seals Kevlar fabric reinforced Vee packing is a stacked, multi-lip sealing solution crafted from high-strength woven Kevlar fibers, engineered specifically for demanding reciprocating shaft applications. Designed as a series of interlocking V-shaped rings, it delivers exceptional pressure resistance, wear durability and leak-tight performance in high-pressure fluid systems. The robust Kevlar construction stands up to abrasive media, heavy loads and continuous cyclic motion, ensuring long-term reliability in industrial pumps, compressors and process equipment.
Split oil seal is mainly an industrial oil seal, and can also be used as an automotive oil seal for commercial vehicles and special vehicles
Forever Seals Kevlar reinforced U-ring seal is crafted with high-tensile Kevlar fiber combined with specialized rubber compound, forming a robust U-shaped cross-section. The woven Kevlar layer delivers exceptional tear strength and anti-extrusion performance, while the rubber matrix ensures reliable elasticity and sealing contact. This composite construction stands up to heavy loads, high pressure shocks and abrasive fluid environments, maintaining stable sealing in reciprocating hydraulic equipment.
