Thermowell Immersion Sleeve OTOTEC 304 Steel G 1/2 Thread 10pcs

Description

Product Overview

The OTOTEC Thermowell Immersion Sleeve is engineered for demanding temperature monitoring applications where reliability and precision are paramount. Constructed from 304 stainless steel, the sleeve delivers exceptional resistance to corrosion, scaling, and chemical attack, ensuring a long service life even in aggressive industrial environments. The material choice also provides excellent thermal conductivity, which helps maintain accurate sensor readings by minimizing temperature gradients across the housing.

The design incorporates a standard G 1/2 inch male pipe thread, a widely accepted connection size that simplifies installation on a broad range of process piping and instrumentation. This thread dimension allows the sleeve to accept sensor lines up to 6 mm in diameter, making it compatible with most thermocouples and RTDs used in HVAC, water heating, and laboratory settings. The internal bore is precisely machined to provide a snug fit for the sensor while avoiding excessive stress that could affect measurement accuracy.

Dimensions are carefully balanced to fit within tight spaces without sacrificing structural integrity. The overall package measures 4.69 x 2.83 x 0.87 inches and weighs only 3.17 ounces per unit, which reduces the load on supporting structures and eases handling during installation or maintenance. The product is supplied as a set of ten immersion sleeves, offering sufficient inventory for multiple installations, routine replacements, or spare parts inventory.

Beyond the core mechanical attributes, the sleeve is designed with user-friendly features such as a smooth exterior finish that reduces the risk of snagging on adjacent components, and a rounded edge on the insertion side that protects the sensor cable from abrasion. The product does not require any batteries or external power sources, as it functions purely as a protective conduit for temperature sensors.

Usage

The OTOTEC immersion sleeve is ideally suited for a variety of temperature monitoring scenarios. In HVAC systems, it can be installed in air handling units, chillers, and heat exchangers where accurate temperature data is essential for efficient climate control. The sleeve protects the sensor from condensate, dust, and corrosive refrigerants, extending the sensor’s operational life while delivering reliable data to the building management system.

In water heating applications, the sleeve can be placed in boiler feed lines, hot water tanks, and solar thermal collectors. Its stainless‑steel construction resists the corrosive effects of mineral-laden water and steam, while the G 1/2 inch thread ensures a secure connection to standard pipe fittings. This configuration enables precise temperature measurement for safety controls, energy management, and performance optimization.

Industrial machinery, such as pumps, compressors, and process reactors, often operate under harsh conditions that include high pressures, aggressive chemicals, and fluctuating temperatures. The immersion sleeve shields the temperature sensor from direct exposure to these elements, preventing premature failure and reducing maintenance downtime. Its compact size allows it to be integrated into tight spaces where larger protective housings would be impractical.

Laboratory environments benefit from the sleeve’s clean, non‑reactive surface, which is essential when measuring temperatures of sensitive solutions or when maintaining strict contamination controls. The ability to accommodate sensor lines up to 6 mm makes it compatible with a wide range of laboratory-grade thermocouples and RTDs, facilitating accurate data collection for research and quality assurance.

Installation is straightforward: the user threads the G 1/2 inch male end into the corresponding female fitting on the process line, inserts the temperature sensor through the sleeve’s central bore, and secures the sensor using the provided set screw or clamp (if required by the sensor type). No special tools or calibration steps are needed beyond standard sensor verification procedures.

FAQ

What temperature range can the OTOTEC immersion sleeve withstand?

The sleeve’s 304 stainless steel body is rated for continuous operation from -200 °F to +800 °F (-129 °C to +427 °C). This wide range covers most industrial, HVAC, and laboratory applications, ensuring the sleeve will not deform or lose integrity under typical temperature extremes encountered in these settings.

Can the sleeve be used with both thermocouples and RTDs?

Yes. The internal bore is sized to accept sensor lines up to 6 mm, which accommodates standard thermocouple and RTD leads. The sleeve does not interfere with the sensor’s electrical characteristics, allowing accurate temperature measurement regardless of the sensor type.

Is the G 1/2 inch thread compatible with all pipe materials?

The G 1/2 inch male thread is a universal standard that mates with brass, stainless steel, PVC, and other common pipe materials when the corresponding female fitting is used. Proper sealing tape or compound should be applied according to the installation guidelines to ensure a leak‑free connection.

How many sleeves are included in the package and can I order more?

The product is supplied as a set of ten immersion sleeves, identified by part number 064‑BS. Additional quantities can be ordered using the same part number, and bulk pricing is available for larger orders. Contact OTOTEC sales for custom packaging or volume discounts.

What maintenance is required for the immersion sleeve?

Because the sleeve is made of corrosion‑resistant stainless steel, routine maintenance is minimal. Periodic visual inspection for physical damage or buildup of deposits is recommended. If the sleeve becomes fouled, it can be cleaned with a mild detergent and a soft brush; avoid abrasive cleaners that could scratch the surface.
