Danfoss 014-1603 Sight Glass Socket

The Danfoss 014-1603 Sight Glass Socket is a critical SGRH series component designed for professionals monitoring moisture levels and refrigerant state in high-pressure systems. Featuring a rugged brass body and an M20 x 1.5 connection, this socket is engineered to withstand a maximum working pressure (MWP) of 667 psig (46 bar). Its ultra-wide operating temperature range, from -58°F to 175°F, ensures stable performance across diverse refrigeration and air conditioning environments. The integrated N-type moisture indicator provides clear, immediate visual feedback, allowing technicians to identify potential system contamination or suboptimal subcooling before equipment failure occurs. This OEM refrigerant sight glass is fully compatible with modern high-pressure refrigerants, including R410A, R134a, R404A, R448A, and R1234yf. Built for longevity in commercial and industrial HVACR applications, its precision M-type connection ensures a leak-free interface when installed according to standard torque specifications.

Key Benefits for Technicians

• Broad Refrigerant Compatibility: Approved for use with HCFC, HFC, and HFO refrigerants including R410A, R32, and R1234ze.
• High Pressure Resilience: Rated for 46 bar, making it suitable for both liquid lines and high-side applications.
• Precision Moisture Detection: The N-type indicator transitions color to signal moisture presence, essential for protecting compressor oil and preventing acid formation.
• Compact Construction: Lightweight 0.024 kg brass design reduces vibration stress on thin-wall copper tubing.
• Global Compliance: UL Approved (76H4) and C UL US Listed, meeting stringent safety standards for North American and European installations.

Common Questions

Is the Danfoss 014-1603 compatible with POE oils?
Yes, the materials and the N-type indicator are designed to function reliably with Polyolester (POE) and Polyalkylene Glycol (PAG) oils commonly found in R410A and R134a systems.

What is the thread specification for this sight glass socket?
This unit utilizes a metric M20 x 1.5 thread. Always verify your manifold or receiver port size matches this M-type connection to ensure a proper seal.

Can this be used on the high side of a CO2 (R744) system?
While this socket has a high 667 psig rating, it is typically restricted to subcritical cycles. Always check the specific discharge pressures of your system against the 46 bar limit before installation.
