Twisted Square Thermowell
SKU: TWISTED-SQUARE
Specialty barstock thermowell with a patented twisted-square stem profile that dramatically reduces vortex-induced vibration. Designed for high-velocity service where a straight or tapered stem would resonate and fail by fatigue. ASME PTC 19.3 TW-2016 compliance for vortex-induced stress mitigation. Same 114C platform as the standard barstock thermowell, but with Threaded mounting only and the unique Twisted stem style. Wide material selection: 316/316L SST, 304/304L SST, Carbon Steel A-105, 310 SST high-temp, 321 SST, Alloy B-3, Alloy C-276 (Hastelloy). Immersion length 2-40 in / 50-1000 mm.

Required Specifications
6 of 6 selectedTwisted Square supports 2-40 in / 50-1000 mm. Specify the exact length from the line schedule (custom lengths fall in ¼-in or 5 mm increments).
Twisted Square is Threaded-only. For flanged / Van-Stone / welded thermowells use the 114C standard barstock family.
Fixed: Twisted profile. This is the defining feature of the Twisted Square family — the twisted geometry suppresses vortex-shedding-induced vibration.

114P Protection Tube
Tubular protection sleeve for temperature sensors in Chemical and Pharmaceutical industries — different from the 114C barstock thermowell platform. Designed for fast time response (thin wall) or applications requiring long immersion lengths beyond what barstock thermowells economically support. Standard bore diameter 7 mm (0.28 in), tip wall thickness 3 mm (0.12 in); NAMUR-bore variant reduces to 6 mm bore / 5 mm wall. Threaded only — NPT, BSPT, BSPF, and metric process connections. Immersion length 50-2500 mm in 5 mm increments. Materials: 316/316L SST and 316Ti SST.
