FAQ
Is 524511 a direct-fit elbow?
No. It’s a universal 3.5" 45° mandrel bend intended for custom fabrication or repair. Confirm length and routing for your build.
Will stainless outlast aluminized in salted climates?
Yes—stainless generally offers superior corrosion resistance versus aluminized tubing, especially where roads are salted. Routine inspection is still recommended.
What clamps should I use?
Use quality 3.5" lap-joint or band clamps rated for stainless. Match the clamp type to your mating joints for a leak-free seal.
Can I weld this elbow?
Yes. It can be TIG/MIG welded. Prep the joint, use appropriate stainless wire/filler, and confirm orientation before final weld.
