About This Part
Cooling loops reward smooth, concentric flow paths, and this adapter delivers one from a single tube blank. The 304 stainless tube is turned on a CNC lathe to a 2.0 in outside diameter with a 0.88 in bore and a 1.81 in overall length, keeping the flow path round and concentric so junction losses stay predictable.
The drawing follows ASME Y14.5-2009 in imperial units: decimal features at X.X ±0.020 in and X.XX ±0.010 in, angles at ±0.5 degrees, and 63 Ra microinch on general surfaces. Where the design joins tube sections, welds meet AWS D18.1, and every internal and external edge leaves the lathe broken to 0.02 in.
304 brings the corrosion resistance and clean surface that cooling and fluid equipment need, and each piece is fully inspected for size and appearance after turning before it is packed.

Common Questions
Is 304 the right grade for a cooling adapter?
For most water glycol and coolant loops, yes: 304 resists corrosion, cleans up bright, and costs less than 316. If your loop runs chlorides or aggressive chemistry, we will suggest 316 before you commit.
Can you hold the imperial callouts on a metric shop floor?
Yes. This lot was produced and inspected in inches against the ASME Y14.5 drawing, which is routine for export work.
Do you supply the welds or the bare adapter?
Both are possible. Quote from the drawing and we will include AWS D18.1 welding and inspection in the route where the design calls for it.
