Shaft RVA Spring Energized Seal PTFE Carbon Fiber FKV High Temp Corrosion Resistant by IKSONIC CO., LTD.

Description

Product Description

IKSONIC CO., LTD. presents the high-performance Shaft RVA Spring Energized Seal, also known as a FKV (Floating Carbon Fiber) seal or PTFE carbon fiber lip seal. Designed for demanding shaft applications, this seal combines a robust PTFE jacket with a resilient spring element to provide exceptional sealing under high temperatures and corrosive conditions. As a direct China factory manufacturer, we offer custom solutions tailored to your specific shaft dimensions and operating parameters.

Key Features

• High Temperature Resistance: Operates effectively in extreme thermal environments, suitable for continuous use up to 260°C (500°F) depending on material grade.
• Corrosion Resistance: PTFE and carbon fiber construction offers excellent chemical inertness, resisting attack from acids, bases, solvents, and other aggressive media.
• Low Friction & Long Life: The PTFE jacket provides a low coefficient of friction, reducing wear on the shaft and extending seal life.
• Spring Energized Design: The internal spring ensures consistent lip contact and sealing force, compensating for wear, shaft runout, and pressure variations.
• Custom Manufacturing: As a factory, we can produce seals to your exact specifications, including custom sizes, materials, and spring types.

Q&A

Q1: What is the difference between a standard oil seal and a spring energized seal?
A1: Standard oil seals typically use a rubber lip with a garter spring. Spring energized seals use a PTFE jacket with a metal spring, offering superior chemical resistance, wider temperature range, and lower friction.

Q2: Can you provide seals for non-standard shaft sizes?
A2: Yes, as a factory, we specialize in custom manufacturing. Please provide your shaft diameter, housing bore, and operating conditions for a tailored solution.

Q3: What is the typical lead time for custom orders?
A3: Lead time depends on complexity and quantity. Standard sizes may ship within 5-7 working days. Custom orders typically require 10-15 working days.

Q4: Is the carbon fiber filler necessary for all applications?
A4: Carbon fiber reinforcement enhances wear resistance, reduces creep, and improves thermal conductivity. It is recommended for high-speed, high-pressure, or dry-running applications. Other fillers like graphite, bronze, or glass are also available.

Q5: How do I install a spring energized seal?
A5: Installation should be performed carefully to avoid damaging the PTFE lip. Use a tapered sleeve or installation tool. Ensure the seal is pressed squarely into the housing bore. Lubrication is recommended.

Q6: Do you offer samples for testing?
A6: Yes, we can provide samples for evaluation. Please contact our sales team with your requirements.

Q7: What is the minimum order quantity (MOQ)?
A7: For standard sizes, MOQ is typically 10 pieces. For custom sizes, MOQ may be 50-100 pieces depending on complexity.

Q8: Can the spring material be changed for corrosive environments?
A8: Yes, we offer springs in Hastelloy, Inconel, and other corrosion-resistant alloys for aggressive chemical environments.
