Danfoss 8156131 Gasket

The Danfoss 8156131 is a 1 1/4" Discharge Side Gasket engineered specifically for Maneurop reciprocating compressors, including the MT, MTZ, and NTZ series. As a veteran technician knows, maintaining a leak-proof seal at the Rotalock valve connection is critical for system integrity, especially in high-pressure refrigeration and HVAC applications. This PTFE (Teflon) seal is designed to withstand the chemical rigors of modern refrigerants and oils, including 160P mineral oil and POE, ensuring it remains resilient under extreme thermal cycling and discharge temperatures.

Sized accurately for 1-1/4 inch Rotalock fittings, the 8156131 gasket provides the necessary compression to prevent refrigerant loss and atmospheric contamination. Whether you are performing a routine overhaul or a targeted compressor repair, using OEM Danfoss parts ensures exact dimensional fitment and material compatibility, reducing the risk of premature failure associated with generic alternatives. This discharge side gasket is essential for contractors looking to restore factory-spec performance to chillers, heat pumps, and air conditioning units utilizing Danfoss hermetic hardware.

• High-Grade PTFE Construction: Offers superior resistance to refrigerant-oil mixtures and prevents hardening in high-temperature discharge lines.
• Precision Rotalock Fit: Designed specifically for 1 1/4" discharge ports to ensure a permanent, gas-tight seal at the valve junction.
• Broad Compressor Compatibility: Direct replacement for gaskets in Maneurop MT and MTZ series compressors, streamlining inventory for service vans.
• Operational Reliability: Minimizes system downtime by eliminating leaks that lead to low-pressure trips and inefficient cooling cycles.

• Is this gasket compatible with both MT and MTZ compressors? Yes, the Danfoss 8156131 is the standard 1-1/4" seal used for the discharge side on both mineral oil (MT) and POE oil (MTZ) reciprocating models.
• Should I reuse old gaskets during a valve service? No, Teflon Rotalock gaskets are designed for single-use deformation to create a seal; always replace with a new 8156131 whenever the connection is broken.
• Does this seal handle high-pressure refrigerants like R404A and R407C? Yes, the PTFE material is rated for the high pressures and temperatures typical of these refrigerants in industrial and commercial applications.
