Flare Fittings Supplier in Michigan

Crestflo supplies flare fittings across Michigan: 37° JIC flare fittings to ISO 8434-2, and 45° SAE flare fittings in stainless and nickel alloys, sized 1/8" to 2" (3–50 mm) OD. They're rated to 15,000 psi and built as drop-in interchange backed by ASTM F1387. We're a US-serving manufacturer supplying Michigan, not located there. Standard items ship from ready stock. Specials get made to order. Delivery runs 6–8 weeks to your Michigan site or distributor.

Alloy selection gets matched to the service. Hastelloy and Monel cover the Dow/BASF chlor-alkali corridor. NACE MR0175 Inconel and duplex handle Marathon's sour-crude refinery in Detroit.

Scope note: here, a flare fitting means an instrumentation and hydraulic tube connection (37° JIC / 45° SAE). It's not the flare nut you'd find on a domestic gas line or a refrigeration setup.

Flare Fitting Demand Across Michigan: Who Buys Them Here

Michigan's instrumentation market breaks into four clusters, and each one pulls flare fittings for a different high-pressure or hydraulic duty:

Dow runs its global headquarters and Michigan Operations out of Midland, handling specialty silicones alongside legacy chlor-alkali and brine chemistry. BASF Wyandotte, known as "North Works," traces back to the historic Michigan Alkali chlor-alkali operation. Flared alloy connections here serve HCl, wet-chlorine and caustic instrument and utility lines.

Hemlock Semiconductor, based near Saginaw, is the largest US-headquartered producer of semiconductor-grade polysilicon. A new facility there carries backing of up to $325M in CHIPS incentives and handles chlorosilane and HCl service. Clean-gas UHP lines run face-seal, but the high-pressure utility and hydraulic hookups around them take flare.

Michigan's auto and EV-battery sector spans the whole state. The Detroit Big Three anchor it, and the LFP battery build-out adds real weight: Ford BlueOval Battery Park in Marshall, LG Energy Solution in Holland, and Ultium Cells in Lansing. Together they drive demand for 37° JIC hydraulic flare fittings across power units, presses and process skids.

Marathon's Detroit Refinery, the only one in Michigan, processes roughly 146,000 bpd of heavy sour Canadian crude. That H2S exposure means NACE-compliant flare fittings and manifolds are non-negotiable.

In Kalamazoo and Portage, Pfizer's sterile-injectable campus specifies EP 316L high-purity connections. Sanitary lines lean toward face-seal, while the hydraulic and utility side sticks with flare.

Buyers in this market span plant MRO teams, EPC contractors, panel fabricators, OEMs and distributors, all sourcing flare fittings for Detroit, Midland, Saginaw, Kalamazoo, Lansing, Holland and Wyandotte.

Flare Fittings: Also Known As

Michigan specifiers use several names for this same product. Flare fittings also go by 37° JIC flare fittings (SAE J514 / ISO 8434-2), 45° SAE flare fittings (SAE J512 / J513), flared tube fittings, JIC 37-degree fittings, and flare tube connectors. Related instrumentation forms include compression (double-ferrule) tube fittings, DIN 2353 bite-type fittings, and VCR face-seal fittings, which cover the ultra-high-purity lines that flare can't handle.

Flare Fitting Specs at a Glance

Values follow the applicable standard and can be adjusted to fit requirements; every part carries a heat/lot number marking. For full specs and ordering codes, check the flare fittings hub, Crestflo condenses the region-relevant slice on this page.

Recommended Alloys & Specs for Michigan Flare-Fitting Service

In Michigan, the technical wedge comes down to alloy selection matched to the actual stream. Spec the correct alloy for the service; don't reach for a blanket grade.

Alloys link to their material pages for composition and property data. Each one comes only as an instrumentation flare fitting.

37° JIC vs 45° SAE Flare Fittings

Both are all-metal flared tube connections, with no elastomer at the primary seal. That said, you can't swap one for the other.

Confirm the flare angle before ordering. Mix 37° and 45° seats and you'll get leaks. If you need help matching an existing print, ask our engineering team for the ordering-code guide.

Standards, Certifications & Interchange Proof

Crestflo flare fittings meet the standard approvals for each product type: ISO 8434-2 for the 37° flare, SAE J512/J513 for the 45° flare, NACE MR0175 / ISO 15156 for sour service, and ASME B1.20.1 on NPT ends. Compression and flare fittings are qualified to ASTM F1387, which covers dimensional interchange with Swagelok®, Parker® and other major brands. Swagelok® and Parker® remain trademarks of their respective owners. Parts are offered as interchange or equivalent, not "compatible." Crestflo holds ISO 9001 / 14001 / 45001 and PED certification. Every part carries a heat/lot number with an EN 10204 3.1 MTC; 3.2 is available on request. Datasheets and CAD files go out to customers who ask for them. For picking components in sour-crude service, check the NACE MR0175 standard page and the downstream refining industry page.

US-Serving Flare Fittings Manufacturer Supplying Michigan: Lead Time & Logistics

Crestflo doesn't hold a Michigan warehouse, and there's no US-held stock in the state. Product comes from India, though US/European melt is available on request, with full material traceability. Standard items ship from ready stock. Specials get made to order, and delivery runs 6–8 weeks from PO, compare that to the 20+ weeks typical for the majors.

Michigan's Great Lakes gateways reach the Atlantic via the seasonal St. Lawrence Seaway. That's true of both the Port of Monroe (the state's only Lake Erie port, served by Canadian National and Norfolk Southern rail plus I-75) and the Port of Detroit. The Seaway route is seasonal and limited in depth, though, so containerized instrumentation usually comes in through an East Coast or Gulf port instead, NY/NJ, Virginia or Houston, and then moves inland by rail on NS, CSX, CN or CPKC to reach Michigan. That ocean leg plus the inland-rail transit adds time on top of the 6-8-week build. When Michigan MRO needs are urgent, we air-freight the critical line items and send the rest by rail or truck.
