FAQS on felt wiper seals

Q: What are the primary applications of felt wiper seals?

A: Felt wiper seals are commonly used in hydraulic and pneumatic systems to prevent contaminants like dust, debris, and moisture from entering machinery. They also retain lubrication and protect components like rods or pistons.

Q: How do metal clad wiper seals differ from standard wiper seals?

A: Metal clad wiper seals feature a metal casing for enhanced structural integrity and durability in high-pressure environments. Standard wiper seals, often made of felt or polymer, prioritize flexibility and cost-effectiveness for lighter-duty applications.

Q: What factors should I consider when selecting wiper seals?

A: Key factors include operating pressure, temperature range, media compatibility, and environmental contaminants. Felt wiper seals suit low-pressure, low-abrasion scenarios, while metal clad variants excel in harsh industrial conditions.

Q: Can felt wiper seals be used in high-temperature environments?

A: Felt wiper seals are ideal for moderate temperatures but may degrade under extreme heat. For high-temperature applications, metal clad or polymer-based wiper seals with heat-resistant properties are recommended.

Q: How do wiper seals enhance machinery lifespan?

A: Wiper seals prevent contamination ingress and lubricant leakage, reducing wear on moving parts. Felt wiper seals absorb excess oil, while metal clad versions add a robust barrier against abrasive particles.
