Product Overview
This component is a Precision Steel Casting stainless steel sealing cover, precision-machined to protect internal assemblies from contamination, moisture, and mechanical exposure. It features a recessed interior and a central precision-bored hole, providing both sealing and controlled access for fastening or alignment functions. With a compact height of 0.95 inches and wall thickness of 0.15 inches, it ensures reliable enclosure performance in compact mechanical systems.
Material & Surface Treatment
Made from 316L stainless steel, this sealing cover offers excellent corrosion resistance and mechanical strength in demanding environments. After machining, the surface is passivated per SAE-AMS2700, enhancing oxidation resistance and ensuring long-term stability in industrial, marine, and chemical applications. Both internal and external surfaces meet a 32 micro-inch finish requirement for smooth, clean contact surfaces.
Key Features

Central 0.18-inch hole for alignment, fastening, or venting
Smooth internal cavity for enhanced sealing and assembly fit
Corrosion-resistant 316L stainless steel with passivated finish
Tight dimensional control for reliable installation and long-term performance
Produced via Precision Steel Casting for superior quality and repeatability
Typical Applications
Ideal for fluid systems, pressure instrumentation, sealed housings, laboratory equipment, and mechanical enclosures, this part provides dependable protection where cleanliness, corrosion resistance, and controlled sealing are essential. Its Precision Steel Casting origin ensures structural integrity and consistent performance, particularly in environments exposed to chemicals, moisture, or temperature variations.
FAQ
Q: Can you cast and produce parts based on my drawing?
A: Yes. We accept customer drawings (STEP, IGES, SolidWorks, AutoCAD, PDF, etc.) and can manufacture parts via precision casting, then finish with CNC machining or surface treatment as needed to meet your requirements.
Q: What kind of tolerances and surface finish can you guarantee?
A: For precision castings, we typically meet ISO 8062 tolerance classes (CT4–CT6) depending on complexity. With additional machining, tighter tolerances and smoother surface finishes are achievable.
Q: What materials are available for casting?
A: We support stainless steel (e.g. 316L, 304), carbon steel, alloy steel, and other alloys. Material selection will be based on your application requirements (corrosion resistance, strength, wear resistance, etc.).
Q: Do you supply material certificates and inspection reports?
A: Yes - we can provide mill certificates, chemical composition reports, and inspection documentation (dimensions, surface finish, non-destructive inspection if required).
Q: Can precision castings eliminate the need for heavy machining?
A: Often yes. Because our parts are near-net-shape, many designs require minimal machining or finishing, which reduces cost, waste, and lead time - especially beneficial for batch production.
