Marine Spare Parts & Instruments — Gauges, Sensors & Replacement Components
Marine-grade spare parts and instruments: pressure gauges, temperature sensors, mechanical seals, pump spares, and replacement components. Manufacturer class certificates supplied.
Struggling to Source Replacement Parts for Marine Equipment Already in Service?
When a pressure gauge fails, a temperature sensor drifts, or a pump seal leaks mid-voyage, you need the correct replacement part fast — not a 12-week OEM lead time and a premium price tag. hicool supplies marine-grade gauges, sensors, control instruments, and replacement parts compatible with major equipment brands. We cross-reference your existing part numbers, confirm compatibility, and ship within days.
Watch: Gauge replacement: range is not the continuous load limit
This pressure-gauge example covers model-specific steady and fluctuating loading limits. It does not cover every instrument on this page or establish a universal gauge limit.
Illustrative procurement and selection guide; not product footage or performance test evidence. Confirm the final specification for your application.
Send the gauge model, dial size, range, connection, fluid and steady or fluctuating working pressure. Request a quotation: sales@hiqool.com
Marine Spare Parts & Instruments — Multi-Brand Compatible
Our spare parts and instruments catalogue covers 7 product families across measurement, control, and replacement component categories. We supply both OEM-sourced parts (from the original Chinese manufacturer) and equivalent-specification replacements for European, Japanese, and Korean equipment already installed on vessels. Every item is verified for dimensional, material, and performance compatibility before shipment.
Instruments include pressure gauges (bourdon tube, diaphragm, digital), temperature sensors (RTD, thermocouple, bimetallic thermometers), level gauges (sight glass, magnetic, float-type), and flow instruments. Replacement parts include mechanical seals, shaft sleeves, impellers, bearings, gasket sets, filter elements, and control valve internals for pumps, compressors, heat exchangers, and auxiliary machinery.
We serve vessel operators, ship management companies, ship chandlers, and marine service engineers who need reliable parts at competitive prices without the lead time and minimum-order constraints of OEM channels.

Product Range
| Category | Products | Typical Applications | FOB Range (USD) |
|---|---|---|---|
| Pressure Gauges | Bourdon tube, diaphragm seal, digital | Engine room, cargo system | $5–$300 |
| Temperature Sensors | Pt100 RTD, thermocouple (K/J/T), bimetallic | Exhaust, cooling water, cargo | $10–$500 |
| Level Instruments | Sight glass, magnetic level gauge, float switch | Tank, bilge, boiler | $20–$800 |
| Mechanical Seals | Single, double, cartridge type | Pumps (centrifugal, screw) | $30–$1,200 |
| Pump Parts | Impellers, shaft sleeves, wear rings, gaskets | Ballast, bilge, cooling pumps | $15–$2,000 |
| Filter Elements | Oil filter, fuel filter, air filter, hydraulic filter | Engine, hydraulic system | $10–$500 |
| Control Valve Parts | Seats, plugs, diaphragms, actuator springs | Steam, fuel, cooling systems | $20–$1,500 |
OEM Part vs Compatible Replacement — How We Ensure Fit
| Aspect | OEM-Sourced | Compatible Replacement |
|---|---|---|
| Source | Original Chinese manufacturer | Verified equivalent supplier |
| Compatibility | Exact match | Cross-referenced dimensions + material + performance |
| Price | 30–50% below OEM channel | 50–70% below OEM channel |
| Documentation | OEM test report available | Material cert + dimension report |
| Warranty | Manufacturer warranty | hicool quality guarantee |
Rule of thumb: For class-critical instruments (safety systems, cargo monitoring), specify OEM-sourced parts with certificates. For general service instruments and consumable parts (gaskets, filters, seals), compatible replacements offer significant savings with equivalent performance.
Common Applications
- Scheduled maintenance spares for vessel operators and ship management companies
- Emergency replacement of failed instruments during port calls
- Ship chandler inventory for high-turnover consumable parts
- Drydock maintenance packages — bulk orders of seals, gaskets, filters, and gauges
- Retrofit/upgrade of analog instruments to digital equivalents

Spare Parts Procurement Guide
Compile Your Parts List
Don't order piecemeal. Collect requirements across all vessels for quarterly or annual procurement. Bigger consolidated orders = better pricing + lower per-unit freight.
Provide Identification
Part number, OEM equipment model, or nameplate photo. The more information, the faster we cross-reference. Drawing/sketch for custom-machined parts.
Specify Certification Needs
Not all spare parts need class certificates. Gaskets, filters, and bearings usually don't. Pressure-rated parts (valve internals, pump impellers) usually do. Specifying correctly avoids unnecessary certification cost.
Set Up Annual Agreement
Framework agreement with quarterly call-off = fixed pricing for 12 months + priority processing. Most cost-effective for fleet managers with regular spare parts consumption.
