Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
Products
FOREVER SEALS specializes in the research, development, production and sales of industrial sealing parts, providing a diverse product line including ISO-standard products and customized sealing solutions. We use high-performance materials such as PTFE, FKM, etc. to ensure that seals work stably in extreme temperature and pressure ranges (-200°C to 300°C, vacuum to 100MPa+). Our products cover O-rings, hydraulic seals, pneumatic seals, etc., and are widely used in chemical equipment, engineering machinery, automobile manufacturing and other industries. At the same time, we provide OEM/ODM services from design to production to meet the personalized needs of customers.

X‑Ring is a high‑performance four‑lip sealing element with X‑shaped cross‑section, serving as an upgraded alternative to standard O‑rings. It works for both static and dynamic sealing (reciprocating, oscillating, low‑speed rotary motion).
Crafted from carbon black reinforced high-grade polyurethane, its precision U-shaped lip design ensures a tight, adaptive seal on pistons and rods during reciprocating motion—critical for leak-free performance in construction machinery, injection molders, and industrial hydraulic systems. The black formula adds superior UV resistance and anti-oxidation properties for long-term outdoor & heavy-duty use.
AM‑series metal‑cased wiper seal interchangeable with Parker Prädifa AM, ISO 6195‑B, press‑fit dust wiper for hydraulic cylinder rod. NBR/FKM/EPDM available. Max speed 2 m/s. Non‑pressure‑bearing for dust exclusion.
URB seal is a two-piece U-shaped composite reciprocating seal, composed of polyurethane(PU) main sealing body and NBR O-ring energizer. Available for piston rod and piston sealing.
POM (Polyoxymethylene, also known as Acetal / Delrin) semi-finished tube is extruded rigid hollow engineering plastic blank ready for precision machining.
Customers can directly perform CNC turning, drilling and milling to produce bushings, support rings, wear plates, rollers, spacers and mechanical structural parts.

Bronze filled PTFE semi-finished tube is sintered composite tube blank compounded by PTFE matrix and bronze powder (40% / 60% bronze by weight).
NBR (Nitrile Butadiene Rubber) semi-finished tube is vulcanized hollow rubber blank specially designed for CNC turning and machining. It can be processed into custom oil seals, O-rings, gaskets, shaft sleeves and various special-shaped sealing parts without mold opening.
High‑performance FKM DS117 asymmetrical single‑acting rod seal offers reliable static‑dynamic sealing, excellent heat and media resistance for medium‑high‑pressure hydraulic cylinders.
PU semi-finished tube is extruded polyurethane (TPU) hollow blank tube, manufactured from high-quality ester-based or ether-based polyurethane raw materials. It is a semi-finished raw material for further CNC turning, cutting and machining to produce PU seals, bushings, wear sleeves, buffer rings, rollers and other polyurethane elastomer parts.
PU Semi-finished Tube, also known as polyurethane tubular blank, is a professional near-net-shape raw material specially designed for CNC precision turning
Vee Packing Chevron Seal Set High Pressure Hydraulic Reciprocating V Packing for Cylinder Piston Rod
Vee Packing is a typical self-energizing combined seal, composed of a male backup adapter, multiple V-shaped sealing rings and a female pressure adapter.
Forever Seals NAK VG Type Grease Oil Seal is a high-performance rotary shaft sealing component designed for grease-lubricated applications, crafted from premium nitrile rubber (NBR) with precision-molded geometry. Engineered to provide reliable retention of grease and effective exclusion of contaminants, it ensures smooth, maintenance-free operation of low-speed rotating equipment.
