RS PRO Brass Compression Fitting for Use with Thermocouple or PRT Probe, RoHS Compliant Standard 286-721

RS PRO 286-721 is a brass compression fitting specifically engineered for secure attachment of thermocouple or PRT (Platinum Resistance Thermometer) probes into process fittings such as thermowells and flange plates. This fitting ensures the probe is held firmly at the correct immersion depth for accurate temperature measurement.

The compression fitting operates with an outer nut and an inner ferrule, commonly referred to as an ‘olive’. When the outer nut is tightened, it compresses the ferrule around the probe sheath, creating a secure, leak-tight seal essential for maintaining sensor integrity in pressurized environments.

Constructed from corrosion-resistant brass, this fitting offers excellent thermal conductivity, enhancing sensor responsiveness and reliability. The BSPT (British Standard Pipe Tapered) thread ensures compatibility with standard thermowells and bulkheads, providing a firm and leak-proof connection.

This fitting allows quick sensor immersion depth adjustment without compromising sealing performance, enabling flexible installation and maintenance in diverse industrial scenarios.

Typical applications include use in bulkheads, vessels, and thermowells within HVAC systems, manufacturing process lines, and laboratory environments where precise temperature monitoring is critical.

Manufactured from high-quality brass providing corrosion resistance. BSPT tapered thread for reliable sealing with process fittings. Facilitates precise and secure probe placement in thermowells. RoHS compliant, ensuring adherence to environmental safety standards.
