114P Protection Tube
SKU: 114P
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.

Required Specifications
9 of 9 selectedThe 114P is a European-design product — metric is the only unit.
Length of the protection tube that enters the process (50-2500 mm in 5 mm increments). The 114P's strength is supporting longer immersion lengths than a barstock thermowell can economically deliver.
The 114P is Threaded-only — for flanged or weld-in protection, use the 114C barstock thermowell platform.
Straight is the workhorse. Stepped NAMUR has a smaller-diameter NAMUR-compliant tip (6 mm) for compatibility with NAMUR-conformant sensors.
Distance from the process connection to the instrument-side neck. 000 = no extension; common 50-500 mm.
How the sensor / thermometer threads into the top of the tube. A is NPT (North America standard); E and F are metric with environmental seals (copper ring or gasket) included.
Outer diameter × wall thickness. 9 × 1 mm is the workhorse; thicker walls for higher-pressure service.

Twisted Square Thermowell
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.
