Our FKM Double Lip Oil Seals (TC and TG Types) are designed for high-temperature rotary shaft sealing applications, providing reliable oil retention and effective dust protection. Made from high-quality fluorocarbon rubber (FKM), these high-temperature oil seals offer excellent resistance to heat, lubricating oils, fuels, and many chemicals, with temperature resistance up to 200°C depending on the material compound and operating conditions. Featuring a spring-loaded sealing lip and an additional dust lip, these double lip rotary shaft seals help prevent lubricant leakage and protect equipment from dust and external contaminants.
As a professional FKM oil seal manufacturer and supplier, we offer custom FKM shaft seals, TC oil seals, TG oil seals, oil-resistant rubber seals, and industrial rotary shaft sealsin various sizes and specifications, with OEM customization available for automotive, machinery, hydraulic equipment, and other demanding industrial applications.

Quality & Inspection
We apply strict quality control to every oil seal, from raw material to finished product. Incoming materials are tested for hardness, tensile strength, temperature and oil resistance. During production, curing temperature, mold dimensions and sealing-lip precision are monitored in real time. Before shipment, each batch passes dimensional measurement, visual inspection, leakage testing, and pressure and aging tests. With professional testing equipment, standardized procedures, ISO quality management and full batch traceability, every oil seal is accurate in size, tight at the lip and reliable in sealing—delivering consistent, dependable quality for our customers.

FAQs-
How do I choose between FKM and NBR oil seals?
It depends mainly on operating temperature, media and speed. FKM (fluorocarbon) works from −25 to 200°C and resists oils, acids, alkalis and many chemicals, ideal for high-temperature, corrosive conditions and synthetic oils. NBR (nitrile) generally works from −40 to 120°C, offers good mineral-oil and wear resistance at lower cost, and suits normal-temperature general use. Choose FKM for strong solvents, high-temperature oils or longer service life.
-
What are the shaft and housing-bore requirements for installation?
The shaft should be smooth, with a surface roughness of Ra 0.2–0.8 μm and hardness of at least HRC 35 (HRC 45+ for high speed). Add a 15°–30° lead-in chamfer on the shaft and bore and remove all burrs to avoid cutting the lip. A typical housing bore is H8 and the shaft f7/f8; coat the lip and shaft with clean lubricating oil before fitting.
-
Which way should the lips face on a double-lip (TC) seal?
The primary lip (the side with the garter spring) must face the media being sealed—the oil cavity—to retain lubricant. The secondary lip (no spring) faces outward to block dust and contaminants. If sealing is needed on both sides, use a paired-seal arrangement or a dedicated double-acting design.
-
What are the common causes of early leakage?
Typical causes include wrong selection (material/temperature/speed mismatch), oversized shaft or bore, rough or scratched shaft surface, a cut lip or dislodged spring during fitting, reversed lip direction, dry running from insufficient lubrication, excessive shaft eccentricity or run-out, and contaminated grease. Follow the installation guide and check shaft alignment.
-
What is your MOQ?
Small MOQ for standard stock products. Custom molded items will be quoted separately; small batch sampling is supported.
-
What is your lead time?
Stock items: 3-7 days. New mold sampling:7-15 days. Mass production: 20-30 days after sample approval.
