Aerospace Clamps

With roughly 5,700 clamp line items in the Instaparts catalog of 266,000+ aerospace parts, we cover the hardware that keeps an aircraft's arteries in place. Every hydraulic line, fuel line, duct, and wire bundle is supported at engineered intervals, and the clamp callout defines the band material, cushion compound, and diameter for each of those supports. A clamp with the wrong cushion can chafe a harness or degrade in fuel, so substituting "a clamp that fits" is never acceptable in aerospace.

The specification landscape centers on two families. AN742 plain loop clamps handle rigid tubing and general supports where no cushion is required. MS21919 cushioned loop clamps are the standard for fluid lines and wire harnesses: the letter group in the part number identifies band and cushion materials, and the trailing number gives the nominal diameter, typically in sixteenths of an inch. Beyond loop clamps, V-band coupling styles join flanged duct and engine plumbing sections where fast assembly and high temperatures rule out conventional flanged joints. Instaparts catalogs these families along with related support hardware, so you can search and quote by exact part number.

Every clamp we supply moves through our AS9120 Rev B certified quality management system. Instaparts, a division of RFQ2Go, Inc. based in Toronto, Canada, sources exclusively from approved suppliers and applies counterfeit-prevention controls aligned with AS6081. Shipments include certificates of conformance, and lot traceability is maintained from receipt through delivery, so even routine routing hardware arrives with its pedigree intact.

Clamp installations are finished with attaching hardware from the same drawing. Most callouts pair the clamp with aerospace screws, aerospace nuts, and aerospace washers to complete the support. If your requirement covers multiple categories or a long bill of materials, send it through our quote page and our team will price the complete package.
