RS PRO Stainless Steel Compression Fitting with BSPP Parallel Thread_x000D_ From RS PRO a high-quality 303 stainless steel compression fitting or compression gland for attaching the probe of your thermocouple or RTD (Resistance Temperature Detector) securely into process fittings such as flange plates and thermowells. This stainless steel compression fitting also provides a quick and convenient way of securing your probe at the correct immersion depth into the process it is measuring._x000D_ How Does a Compression fitting Work?_x000D_ A compression fitting comprises of an outer compression nut and an inner compression ring or ferrule also called an ’olive’. The male thread of the fitting is screwed into the thermowell or bulkhead. The probe is then inserted into the aperture at the top of the fitting to the required length. The outer compression nut is then tightened which forces the olive to compress around the outer sheath of the probe. The probe is then held securely in place and a tight seal provided._x000D_ Features and Benefits_x000D_ • Enables secures connection of a probe into a thermowell or bulkhead_x000D_ • Quick and easy adjustment of sensor immersion length_x000D_ • Resistance to pressure applications_x000D_ • BSPP parallel thread_x000D_ • 303 stainless steel for durability and corrosion resistance_x000D_ Application_x000D_ These compression fittings are used for fixing thermocouples in bulkheads, sealing sensors in vessels and securing probes into thermowells or thermopockets_x000D_ Accessories_x000D_ Locknuts are available for these compression fittings_x000D_ Stock number 762-1171 is a locknut for a BSPP 1/8 fitting_x000D_ Stock number 762-1174 is a locknut for a BSPP 1/4 fitting_x000D_ Stock number 762-1178 is a locknut for a BSPP 1/2 fitting
