Msa Safety 813723 O2 Sensor Kit with Gasket

Product Description

The MSA SAFETY 813723 is an oxygen sensor kit designed for use in gas detection instruments that require accurate O2 monitoring. The kit includes a replacement oxygen sensor along with the associated gasket, O-ring, and washer needed to complete a proper sensor swap. This type of kit is typically serviced by safety technicians, industrial hygienists, or instrumentation specialists maintaining confined space entry equipment or fixed gas detection systems.

Oxygen sensor kits like the 813723 are used in environments where monitoring ambient oxygen levels is critical to worker safety. Typical applications include confined space monitoring, industrial facilities, and hazardous location environments where O2 depletion or enrichment poses a risk. The included sealing components — gasket, O-ring, and washer — help maintain the integrity of the sensor housing after replacement.

Key Features

• Complete sensor replacement kit includes gasket, O-ring, and washer for a full-service swap
• Designed for oxygen (O2) gas detection applications
• Sealing hardware included eliminates the need to source components separately
• OEM part number 813723 ensures correct fitment for compatible MSA SAFETY instruments

Compatibility

Designed as an OEM-style replacement O2 sensor kit for compatible MSA SAFETY gas detection instruments. Refer to your instrument service manual or MSA SAFETY documentation to confirm fitment before installation.

Installation Notes

Sensor replacement on gas detection instruments should be performed by a qualified technician familiar with the specific instrument model and applicable safety protocols. Power down the instrument and allow it to reach a safe state before opening the sensor housing. Replace all included sealing components — gasket, O-ring, and washer — during each sensor service to maintain housing integrity. After installation, allow the instrument to complete its warm-up and calibration cycle before returning it to service.
