RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |

Product Details
RS PRO Brass Compression Fitting with BSPP Parallel Thread
From RS PRO a high-quality brass 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 brass compression fitting also provides a quick and convenient way of securing your probe at the correct immersion depth into the process it is measuring
How Does a Compression fitting Work?
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.
Features and Benefits
• Enables secures connection of a probe into a thermowell or bulkhead
• Quick and easy adjustment of sensor immersion length
• Resistance to pressure applications
• BSPP parallel thread
• Brass provides corrosion resistance and good thermal conductivity
Application
These brass compression fittings are used for fixing thermocouples in bulkheads, sealing sensors in vessels and securing probes into thermowells or thermopockets
