Each bar is matched to its mill certificate and heat number before cutting, so the 316L on your drawing is the 316L in your parts, traceable to the lot.

Divine Precision
Made-to-print VCR-type fittings: glands, nuts and gaskets, electropolished and packed particle-free.
These VCR-type fittings are cut to your drawing, with machining tolerances of ±0.005 mm on ground diameters. Small-diameter glands and nuts can run on Swiss turning lines, larger bodies on CNC turning. Send your drawing for a quote.

316L is the default for wetted parts. Electropolishing, passivation and ultrasonic cleaning are what take the parts to a high-purity standard.
Each bar is matched to its mill certificate and heat number before cutting, so the 316L on your drawing is the 316L in your parts, traceable to the lot.
Piece one goes to the CMM. You receive the measurement report and sign it off before the rest of the lot is cut.
Operators pull samples against an AQL plan while the lot runs, so a drifting sealing-face or thread dimension is corrected mid-run.
All parts in a lot get a 100% dimensional and visual check, then cleaning and particle-free packing. The material certificate and inspection record go in the box. Have a gland, nut or gasket drawing ready? Request a quote and the first-article report arrives before production.
Metal-to-metal face seals replace elastomer O-rings where gas purity or vacuum integrity matters. Fluid-power connections belong to hydraulic and pneumatic fittings instead.
Process-gas panels and vacuum lines in semiconductor tooling.
Carrier-gas lines on analytical instruments and vacuum manifolds.
Gas and vacuum feeds on solar-cell and battery-cell process tools.
Clean gas feeds on automated process and inspection stations.
Metal-sealed gas delivery to battery and powertrain test benches.
Gas connections on display and electronics production tools.
Sourcing VCR-type parts? Our team answers within one business day.
Ask a QuestionVCR fittings are metal gasket face-seal connectors. A gland, a nut and a replaceable metal gasket form a metal-to-metal seal for clean gas and vacuum lines. Ours are VCR-type parts made to your drawing.
VCR is a Swagelok trademark for its metal gasket face-seal line, not a generic standard name. That is why we call our parts VCR-type: they are machined to your drawing and never presented as Swagelok products.
Swagelok owns the VCR brand and makes the original line, which distributors resell. Divine Precision does not sell Swagelok parts. We machine VCR-type glands, nuts and gaskets to your drawing at our Dongguan factory.
We build to your print, or to a sample we measure through reverse engineering. Fit with your existing parts is confirmed on the first article, and you receive the FAI report before the batch runs.
A single gland, nut or gasket is a valid order. A first sample can ship in as little as 3 days, usually within 2–3 weeks, via prototype and low-volume production. Full lots typically run 4–6 weeks; rush slots are quoted per job.
A STEP or IGES model plus a 2D drawing with GD&T is ideal. We also accept SolidWorks, ProE, PDF and DWG files. Add quantity, material (such as 316L), finish and packing needs. An NDA is available on request.
