Frequently Asked Questions Q1: What is FKM (Viton®)? A: FKM, commonly known as Viton®, is a high-performance fluoroelastomer. It features excellent resistance to high temperature, mineral oil, fuel, hydraulic fluid and many hydrocarbons for critical sealing. Q2: What temperature range can FKM O-rings work at? A: Typical working range: -20°C ~ +200°C. Special low-temperature FKM grades can reach down to -40°C. Q3: What media are NOT suitable for standard FKM? A: Standard FKM is incompatible with ketones, esters, amines, hot steam and low-molecular-weight acids. Special FKM formulations are required for these conditions. Q4: What sizes of FKM O-rings do you supply? A: We offer standard sizes to AS568, ISO 3601, DIN 3771, JIS B2401, plus custom molded O-rings with non-standard ID, OD and cross-section. Q5: What hardness options are available? A: 60 / 70 / 75 / 80 / 85 / 90 Shore A. 75 Shore A black general-purpose FKM is our most popular stock grade. Q6: Can you provide material certificates?

Frequently Asked Questions 1: What is FKM gasket? A: FKM gasket, also known as Viton / FPM gasket, is a high-performance fluoroelastomer static sealing part, made by compression molding or cutting. It features excellent resistance to high temperature, oil, fuel, solvent, ozone and aging. Q2: What is the temperature range of standard FKM gasket? A: Continuous working temperature: **-20°C ~ +200°C**. Intermittent peak temperature can reach 230°C. Special low-temperature FKM grade can work down to -40°C. Q3: What hardness is available for FKM gasket? A: Common hardness range: **55–90 Shore A**. 70 Shore A is the most popular grade for general static gaskets, like our custom green molded FKM gasket. Q4: What media does FKM gasket resist? A: It works well with mineral oil, synthetic oil, gasoline, diesel, biodiesel, hydraulic fluid, aromatic solvents, dilute acid, hot air, ozone and UV. Q5: What media is NOT suitable for FKM gasket? A: Not recommended for hot concentrated alkali, ketones, esters, some amines and high-pressure saturated steam. Choose AFLAS, EPDM or FFKM for these conditions. Q6: Can you make custom FKM gaskets? A: Yes. We support custom molded FKM gaskets according to your drawings or samples, including custom shape, size, color and hardness. Green 70 Shore A is available as shown. Q7: What certifications can you provide? A: RoHS, REACH, FDA, IATF16949 documents are available upon request. Q8: What industries use FKM gaskets? A: Widely used in automotive, oil & gas, petrochemical, chemical, hydraulic, pump & valve, food & pharmaceutical and compressor systems. Q9: What is the difference between FKM and FFKM gasket? A: FKM is cost-effective for most high-temp oil & chemical conditions. FFKM (perfluoroelastomer) offers superior chemical resistance and higher temperature resistance with higher cost. Q10: Is FKM gasket for static or dynamic sealing? A: FKM gasket is mainly designed for **static sealing (flange, housing joint)**. For dynamic shaft sealing, FKM oil seals are recommended.

Frequently Asked Questions Q1: What is a rubber grommet? A: A rubber grommet, also known as cable grommet or wire grommet, is a molded rubber fitting inserted into panel holes. It protects cables, wires and hoses from sharp edge cuts, provides strain relief, insulation, dustproof, splash sealing and vibration damping. Q2: What material options do you offer for rubber grommets? A: We have EPDM, NBR, silicone, FKM, neoprene and natural rubber. EPDM is the best choice for outdoor, UV, ozone and hot water conditions, not suitable for oil & fuel. Q3: What is the temperature range of EPDM rubber grommet? A: Standard sulfur-cured EPDM: -40°C ~ +120°C continuous use, intermittent peak up to 150°C. Peroxide cured EPDM can reach -40°C ~ +150°C continuously. Q4: What shapes of grommets can you produce? A: Round, oval, square, rectangular, double-sided, split, single-hole, multi-hole and irregular custom shapes. We make products according to your drawings or samples. Q5: What hardness is available? A: Hardness range: 40 ~ 90 Shore A. Common selections: 50A, 60A, 70A, 80A. 70 Shore A is widely used for general cable protection. Q6: Where are rubber grommets applied? A: Mainly for automotive wire harness, EV firewall, electrical cabinets, junction boxes, solar inverters, charging piles, marine wiring, HVAC, outdoor lighting and industrial machinery. Q7: Is EPDM grommet oil resistant? A: No. EPDM has poor resistance to mineral oil, gasoline, diesel and hydrocarbon solvents. Choose NBR grommet for oil environments, FKM for high temp oil and chemicals. Q8: Can you make custom color and size rubber grommets? A: Yes. We support custom size, thickness, hole layout, color and hardness. OEM & ODM molded service is available. Q9: What certifications can you provide? A: RoHS, REACH, IATF16949, ISO9001 documents can be supplied upon request. Q10: How to install rubber grommet? A: It is snap-in installation. Stretch the grommet slightly and press it into the pre-drilled panel hole, then pass cables or hoses through the inner bore.

Xiamen Lead Rubber had the great pleasure of welcoming our valued overseas customer for an on-site factory tour recently. The customer joined our team for in-depth communication over a business lunch, where we exchanged ideas on rubber sealing components, custom molded parts, material formulations including NBR, self-lubricating NBR, FKM, EPDM and project requirements. Following the meeting, our team accompanied the guest to walk through our full production facility. They visited our mold machining workshop, reviewed mold steel stock and CNC machining lines for custom mold fabrication, and observed our compression molding production area. Our operator demonstrated the demolding process of rubber molded seals on the hydraulic press. During the tour, we introduced our in-house mold development capability, quality control workflow, raw material compliance management (RoHS, REACH, Prop 65, PFAS, FDA options), and IATF16949 & ISO9001 quality system. The customer showed strong interest in our self-lubricating NBR compound and custom rubber-to-metal bonded parts for dynamic sealing applications. This face-to-face visit built stronger trust and mutual understanding. We discussed upcoming sample development, technical specifications and long-term cooperation plans. Lead Rubber keeps focusing on custom rubber molding, extrusion, precision mold making and strict quality inspection. We are ready to support customers with reliable sealing solutions for automotive, hydraulic and industrial markets. We look forward to a successful long-term partnership with this customer.
