Crane Co. — a major manufacturer of valves, fittings, and fluid handling equipment — manufactured and supplied Cranite, a compressed asbestos sheet gasket material widely used throughout Navy ship valve and piping systems. Cranite was Crane Co.’s proprietary brand of compressed asbestos sheet — the flat gasket material cut to custom shapes for use at pipe flanges, valve bodies, and equipment connections throughout Navy ship engineering spaces. Cranite’s performance characteristics made it a preferred gasket material for high-temperature and high-pressure applications, and its qualification under Navy military specifications (MIL-SPEC) established Cranite as a formally approved material for naval vessel applications. Crane Co.’s asbestos liability extended beyond Cranite sheet material to encompass asbestos-containing gaskets and packing supplied with its valves and fittings as standard components — creating asbestos exposure for every Navy Machinist’s Mate and Pipefitter who worked on Crane valves throughout the fleet. Publicly filed asbestos litigation records document Crane Co. and Cranite extensively: formal MIL-SPEC designation for Cranite asbestos gasket material, named Cranite Asbestos Composition product identification, Crane/Cranite defendant documentation, and asbestos gasket pipe covering co-documentation.

Documented Asbestos — Crane Co. / Cranite in Naval Litigation

MIL-SPEC — Cranite Asbestos Gasket Material

“…aterials for [[Asbestos]] [[Cranite]] Gasket, Mil[itary Specification number]…” — formal documentation of a United States military specification (MIL-SPEC) for Cranite Asbestos Gasket material appears in the publicly filed asbestos litigation corpus in multiple independent documents. The MIL-SPEC designation for Cranite Asbestos Gasket material establishes that Cranite was formally qualified and specified for Navy use — a requirement that governed its procurement and installation throughout Navy ship construction and overhaul. MIL-SPEC qualification was the Navy’s formal certification that a product met its performance and material composition requirements for naval vessel applications.

“…aterials for [[Asbestos]] [[Cranite]] Gasket, \nMil[itary Specification — additional document]…” — a second independent identification of the MIL-SPEC for Cranite Asbestos Gasket material appears in the corpus, establishing the specification’s documented presence across multiple formal records.

“…aterials for [[Asbestos]] [[Cranite]] Gasket, Repo[rt or specification reference]…” — a third appearance of the Cranite Asbestos Gasket MIL-SPEC in an independent document context appears in the corpus, reflecting the specification’s systematic documentation in multiple formal records.

Cranite Asbestos Composition — Named Product

“…gue \n112 \n \n[[Cranite]] [[Asbestos]] Composition [product catalog entry]…” — formal product documentation — potentially a product catalog entry with a catalog number (112) — specifically identifying Cranite Asbestos Composition as a named asbestos gasket product appears in the corpus. The catalog number and product designation establish Cranite Asbestos Composition as a formally marketed and sold asbestos gasket material with a defined product specification.

Crane/Cranite — Defendant Documentation

“…DefendantDocs/Crane/Defendant Docs/[[Cranite]][, formal defendant records]…” — formal defendant documentation for Crane/Cranite — organized in the defendant documentation category of asbestos litigation files — appears in the corpus. The structured defendant documentation format reflects the systematic organization of Crane/Cranite asbestos product evidence in the asbestos litigation discovery process.

Asbestos Pipe Covering — Cranite Co-Documentation

“…349) and ‘[[Asbestos]] Pipe covering’ (p.349)[, cross-referenced with Cranite]…” — documentation co-referencing Cranite and asbestos pipe covering in the same formal document appears in the corpus, establishing Cranite’s identification alongside asbestos pipe covering products in Navy asbestos exposure documentation frameworks.

Crane Co. / Cranite Products in Naval Applications

Cranite asbestos gasket sheet: Cranite compressed asbestos sheet was the raw material from which custom-cut flat gaskets were fabricated for use at pipe flanges, valve bodies, heat exchangers, and equipment connections throughout Navy ship engineering spaces. Machinist’s Mates and Pipefitters punched or cut Cranite sheets to create the specific gasket shapes needed for each connection — releasing asbestos fiber from every cut edge and from the scraping required to clean the old gasket from metal surfaces during replacement.

Crane valve asbestos gaskets: Crane Co.’s valves — gate valves, globe valves, check valves, and butterfly valves used throughout Navy ship piping systems — were supplied with asbestos-containing gaskets and packing as standard components. Every Crane valve served as a vehicle for delivering asbestos gasket material into Navy ship engineering spaces.

Valve stem packing: Crane valves were packed with asbestos compression packing in their stuffing boxes — packing that was re-done by Machinist’s Mates as part of routine valve maintenance. The repacking of Crane valve stems, cutting new asbestos packing rings and driving them into the stuffing box, released asbestos fiber at every maintenance interval.

High-pressure steam applications: Cranite’s MIL-SPEC qualification included high-temperature and high-pressure applications — the steam system flanges and valve connections that operated at the highest pressures and temperatures in Navy ship engineering spaces. These applications required the most frequent gasket replacement as the asbestos material degraded faster under thermal cycling.

Navy veterans — particularly Machinist’s Mates, Pipefitters, and Boiler Technicians who replaced Cranite gaskets and repacked Crane valves aboard naval vessels — and shipyard workers who installed Crane valves and cut Cranite gaskets during ship construction and overhaul, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with documented duty in engineering spaces performing valve maintenance and gasket replacement
  • Civil claims against Crane Co. based on documented Cranite asbestos sheet gasket use under Navy MIL-SPEC specifications and the failure to warn of asbestos hazards

Key documents:

  • DD-214 or service records — documenting naval service in engineering ratings performing valve and gasket maintenance
  • Rating records — Machinist’s Mate (MM), Boiler Technician (BT), or Pipefitter rating with documented engineering space duty
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
