Tamrotor Marine Compressor TMC NT0114 Plug

Tamrotor Marine Compressor TMC NT0114 Plug (8pcs Set) – New

The Tamrotor Marine Compressor TMC NT0114 Plug is a precision manufactured, high integrity fluid containment plug for crucial seal sites throughout TMC marine rotary screw compressor air ends, oil separation receivers and manifold assemblies. Designed for tough, continuous duty marine use, this plug preserves an air tight and leak proof seal integrity while subjected to dynamic working pressure (7 to 13 bar) and high operational temperatures up to 110°C.

The NT0114 plug is designed specifically to avoid pressure loss, lubricating oil carryover and moisture infiltration in tough engine-room conditions, ensuring reliable performance in shipboard service air, control air and nitrogen generator feed systems. This offering is for a complete factory set of 8 pieces, great for routine overhaul, main engine air system maintenance, or emergency onboard spares inventory.

Model Details

• Manufacturer: Tamrotor Marine Compressors (TMC)
• Part Description: Threaded Port / Oil Drain & Receiver Sealing Plug Set
• Manufacturer Part Number (MPN): NT0114
• Kit Quantity: 8 Pieces (Priced and shipped as a batch of 8)
• Country of Origin: Finland / OEM Global Distribution

Key Features

1. Heavy-Duty Marine-Grade Construction: Fabricated from high-tensile, corrosion-resistant alloy steel engineered to resist vibration-induced loosening, thermal cycling, and marine atmospheric degradation.
2. Precision CNC Threading: Features standardized metric/BSP parallel threads with chamfered leading edges to ensure tight, gall-free engagement into compressor housing ports.
3. Integrated Seal Recess: Designed with a machined shoulder seating surface for standard copper/bonded seal washers (e.g., NT0303 sealing rings), preventing high-pressure fluid migration.
4. High Thermal & Chemical Resistance: Compatible with synthetically formulated marine compressor oils (ISO VG 46 / VG 68 diester and PAO-based fluids) without seal degradation.
5. OEM Drop-In Fitment: Manufactured to exact Tamrotor factory tolerances to ensure immediate installation without line modification or thread re-tapping.

Chief Engineer’s Technical Insight:

During routine air compressor overhauls or oil separator maintenance on TMC units, mechanics frequently strip or gall threads on service plugs due to over-torquing or re-using hardened copper washers. Operating with a weeping plug leads to micro-vibrational air loss and ambient pressure drops in service air headers.”

Applications

• Marine Main Engine Service Air Systems: Sealing access and drain ports on 7-8 bar general service air lines.
• Shipboard Control Air Supply: Maintaining tight seals on instrument air skids supplying pneumatic valve actuators and governors.
• Onboard Nitrogen Generation (N2 Feed): High-duty compressor skids supplying raw air to membrane N2 systems on chemical and gas tankers.
• Oil Separation Receiver Maintenance: Port blocking and service connections for oil drain or temperature sensor access points.

Frequently Asked Questions

What is the Tamrotor TMC NT0114 plug used for?

The TMC NT0114 plug is an OEM threaded seal plug used to cap auxiliary ports, drain points, and service tapping locations on Tamrotor rotary screw air compressors installed on ships and offshore vessels.

Are these NT0114 plugs original Tamrotor components?

Yes, these plugs are original, unused marine surplus items manufactured to meet Tamrotor Marine Compressor (TMC) strict factory specifications for pressure retention and oil compatibility.

Which TMC compressor models accept the NT0114 plug?

The NT0114 plug is widely used across TMC 105, 150, 180, and 235 series compressors, as well as F-series marine screw air units (such as F37-8 EAA).

What sealing gasket should be paired with the NT0114 plug?

It is recommended to pair the NT0114 plug with the OEM NT0303 gasket or equivalent copper/bonded sealing washer to ensure a complete, pressure-tight seal.

Can I buy individual NT0114 plugs or only the 8-piece set?

This specific listing is offered as a complete 8-piece set, ensuring shipboard engineers have sufficient spares for multiple maintenance cycles or total skid overhauls
