Tynulox 3/4″ OD 304 Stainless Steel Tube (2 Pcs)
Tube Size: 19mm (3/4″) OD with a 1.5mm (3/50″) wall and 16″ length. Pack of 2. Material is 304 stainless steel, offering high strength and weldability. Surface treatment uses a polishing process for a durable, attractive finish. Suitable for structural framing, supports, and custom fabrications where weld quality matters.
Etauwe 3/4 Inch OD Round Metal Pipe, 12″ Length
Size is 3/4″ (19mm) OD, 12″ (305mm) length, with a 1.5mm wall thickness. Made from high-strength 304 stainless steel with smooth surface polishing for durable, long-term use. This tubing supports welding and cutting for diverse projects, with emphasis on reliability and versatility for DIY and industrial tasks.
Vigorous 3/4″ OD x 3 Ft. 304 Stainless Steel Tube
This is a 3/4″ OD, 3 ft long seamless 304 stainless steel tube with a 3mm wall thickness. 304 stainless offers corrosion resistance and strength while remaining easy to maintain. The seamless design helps with consistent bore and predictable performance under bending or shaping operations, suitable for frames and DIY crafts.
GeilSpace 3/4″ 304 Stainless Steel Pipe 24″ (2 Pcs)
Size is standard 3/4″ NPS, 24 inches long with a 1.05″ outside diameter and 0.113″ (2.87mm) wall thickness. This set includes 2 pieces and adheres to ASTM-A312 with a rust-proof, corrosion-resistant finish. Ideal for structural applications, supports, and DIY metal projects requiring robust tubing.
GeilSpace 3/4″ 304 Stainless Steel Pipe 48″ (2 PCS)
Length is 48 inches, outside diameter 1.05″ with a wall thickness of 0.113″ (2.87mm). A set of 2 pieces designed for heavy-duty industrial metal tubing needs. conforms to ASTM-A312, rust-proof, and corrosion-resistant for long-term performance in workshops and manufacturing settings.
Hicarer 2 Pcs 3/4″ OD 304 Stainless Steel Tubing, 24″ Length
This pair offers 2 pieces of 24″ tubing with 3/4″ OD and about 1.5 mm wall thickness. Made from 304 stainless steel, the tubes are rust-proof and wet-proof with a bright, smooth surface. Suitable for home furnishing applications, machinery, and general metal fabrication, with tolerances that reflect metric production practices.
Buying Guide
Key purchase considerations include material grade, wall thickness, length options, and finish. For corrosion resistance in humid or outdoor environments, 304 stainless steel is a standard choice. Wall thickness affects bending strength and overall rigidity; thicker walls improve stiffness but add weight. Length availability matters for project planning; modular sets can reduce waste. Weldability is essential for frames and supports, so choose tubes advertised as weldable with a smooth interior bore. Compatibility with fabrication tools (cutters, saws, and welding equipment) should guide your selection. Also consider whether you need a polished surface for aesthetics or a standard industrial finish for workpieces.
Comparison at a glance:
- Shorter lengths (12″ to 16″) are ideal for quick prototypes and smaller frames.
- Longer lengths (24″ and 48″) reduce joints in larger structures but may require more handling.
- Some sets include two pieces, which is cost-effective for symmetrical builds.
- Seamless tubes offer higher bending tolerance but can be more challenging to source.
- Finish options range from polished to standard rust-resistant finishes; match to your project’s aesthetic and environment.
Always verify product specs with the seller for the exact bore, wall thickness, and finish before purchasing, and ensure compliance with any project-related standards or codes.
