FAQ's of Dowty seal:

Q: How do I correctly install a Dowty seal for optimal performance?

A: To install a Dowty seal, place the flat washer with the rubber insert between the mating surfaces of the fitting and tighten to create axial compression. This ensures both dynamic and static sealing capability for leak-proof performance.

Q: What are the main benefits of using a Dowty seal in hydraulic systems?

A: Dowty seals provide superlative sealing under high pressure, resist corrosion (especially when using stainless or plated versions), and are compatible with a range of fluids commonly used in hydraulic equipment. Their design also ensures easy, self-centering installation.

Q: Where can Dowty seals be used effectively?

A: Dowty seals are especially suitable for hydraulic fittings, high-pressure fluid lines, and fluid transfer systems found in industrial, automotive, and machinery settings, thanks to their robust construction and dependable sealing properties.

Q: What is the recommended process if I want to reuse a Dowty seal?

A: Although Dowty seals are designed for single-use, they can potentially be reused if undamaged. Ensure the seal's rubber and metal components are intact and free of deformation before reinstalling to maintain reliable sealing.

Q: When can I expect shipment after placing a purchase order?

A: Dowty seals in standard sizes are stock ready, so you can expect quick dispatch, often on the same or next business day. For custom or large orders, our team will communicate lead times based on current production schedules.
