Craftsman 919175260 air compressor Parts

Most air compressor parts are not interchangeable across brands or even across different models from the same brand. For a Craftsman air compressor like model 919175260, internal components (pump parts, valves, seals, and motor-start parts) must match the exact design so the compressor builds pressure safely and runs correctly.

What’s usually model-specific (not interchangeable)

These parts are engineered around the pump design, pressure rating, and motor load, so swapping “close enough” parts often causes leaks, poor performance, or hard starting:

• Pump components (cylinder, piston, connecting rod)
• Reed valves and valve plate parts
• Head gasket and seal kits
• Pressure switch and unloader setup
• Check valve style and port orientation
• Regulator body and manifold layout

What’s sometimes interchangeable (with careful matching)

Some external connection parts can be shared, but only when you match the connection standard and size.

• Quick-connect couplers and plugs (industrial, automotive, ARO styles)
• Hose fittings and adapters
• Thread type and size (commonly NPT in the U.S.)
• Pressure gauge range (PSI rating) and mounting style

Quick check table: “Can I swap this part?”

Part type	Often interchangeable?	What must match
Pump internals	No	Pump design, tolerances, materials
Pressure switch	Sometimes	Cut-in/cut-out range, amperage, port size, unloader port
Check valve	Sometimes	Tank port size, flow direction, unloader line connection
Couplers/plugs	Often	Coupler series, thread size, sealing method
Gauges	Sometimes	PSI range, thread size, location clearance

Why it matters

Air compressors depend on tight sealing and correct pressure control. A mismatched valve, gasket, or pressure-control part can prevent the tank from building pressure, make the unit short-cycle, or cause constant air leaks that overwork the motor.

Our best way to confirm fit before you buy

Use the model number 919175260 to match parts by application, not by appearance.

• Identify the system: pump, tank, regulator/manifold, or electrical
• Match thread size and thread type (do not force fittings)
• Match pressure ratings (PSI) and airflow needs (CFM) for the application
• If the compressor will not start or struggles under pressure, troubleshoot the unloader/check valve path first

The most common cause of failure on a Craftsman air compressor like model 919175260 is poor maintenance that leads to overheating and accelerated wear. Dirty intake filtration, restricted cooling airflow, moisture in the tank, and running the compressor too hard or too long can quickly damage valves, seals, and the pump.

Most common failure drivers (what we see most often)

• Overheating from blocked cooling fins, poor ventilation, or long run times
• Dirty or restricted intake filter that makes the pump work harder
• Moisture and corrosion from not draining the tank regularly
• Air leaks at fittings, regulator, drain valve, or check valve that increase run time
• Electrical/control issues such as a failing pressure switch, capacitor, or loose wiring

Quick checks you can do first

1. Listen and look: does it struggle to start, trip a breaker, or run continuously?
2. Check airflow: confirm the shroud/vents are clear and the pump area is not packed with dust.
3. Leak test: spray soapy water on fittings and valves; bubbles indicate leaks.
4. Drain the tank: water in the tank is a long-term failure accelerator.
5. Watch the gauges: if tank pressure rises slowly or stalls, suspect pump/valves or a major leak.

Symptom-to-cause cheat sheet

What you notice	Most likely cause	What to check next
Won’t start	Pressure switch, capacitor, motor, unloader/check valve	Air compressor won't start
Runs but won’t build pressure	Leaks, reed valves, piston seal, head gasket	Air compressor won't build tank pressure
Tank loses pressure sitting	Fitting leak, drain valve leak, check valve leak	Air compressor tank won't hold air
Safety valve pops	Overpressure control issue, regulator/check valve problems	Air compressor safety valve keeps popping open

Why it matters

Most “failures” start as small issues that force longer run time. Longer run time raises heat, heat breaks down seals and valves, and performance drops fast. Keeping airflow clear, fixing leaks early, and draining moisture prevents the most expensive pump damage.

Craftsman is a brand name, so Craftsman air compressors (including model 919175260) have been built by different original equipment manufacturers over the years. The actual maker depends on the model and production run; the most reliable way to identify it is by checking the data plate and using the unit’s model and code information.

How to identify who made your Craftsman 919175260

Look for the compressor’s data plate (often on the tank or shroud) and note the details below:

• Full model number: 919175260
• Any additional code, type, or revision number
• Serial number and date code (if shown)
• Electrical ratings (volts, amps) and maximum pressure
• Any small-print manufacturer statement (sometimes lists the OEM)

Common OEMs you may see associated with Craftsman compressors

Different eras of Craftsman compressors have been sourced from different manufacturers. These are commonly referenced for Craftsman air compressors:

• DeVilbiss Air Power (common on many older units)
• Campbell Hausfeld (seen on some older Craftsman models)
• MAT Holdings / Alton Industries (common on many newer Craftsman-branded compressors)

Why it matters

Knowing the OEM helps when you are troubleshooting issues like a pressure switch problem, a check valve leak, or a pump that will not build pressure. It also helps you match the correct style of components (for example, regulator layout, unloader tube routing, and tank fitting types) when you are diagnosing or replacing parts.

Quick troubleshooting cross-check (often confused with “who made it”)

If you are asking because the compressor is acting up, these symptoms usually point to specific systems:

Symptom	Most likely system to check first
Will not start	Power supply, pressure switch, motor, unloader
Will not build tank pressure	Pump, reed valves, head gasket, intake filter
Leaks air after shutoff	Check valve, unloader, fittings
Cannot adjust output pressure	Regulator, gauge, downstream leak

For step-by-step diagnosis, use our DIY guide: air compressor won't start.

What we recommend next

• Write down the full data plate information before ordering parts
• Compare your compressor’s control manifold layout (switch, regulator, gauges) to replacement part photos
• If the pump is weak or noisy, review: how to rebuild an air compressor pump

Yes, it’s worth repairing a Craftsman air compressor like model 919175260 when the problem is a single, serviceable failure (pressure switch, check valve, regulator, gauges, fittings) and the total repair cost is clearly less than replacing the compressor. It’s not worth repairing when the pump or tank is the failure point, or when multiple major issues stack up.

Quick decision checklist

• Repair if the unit runs but has control or leak issues (pressure switch, regulator, check valve, fittings)
• Repair if the motor starts reliably and the compressor builds pressure normally
• Replace if the pump has severe internal wear (low output, overheating, metal noise) after basic checks
• Replace if the tank integrity is questionable (persistent tank leaks or heavy corrosion)
• Replace if repair requires multiple major components at once (pump + motor + controls)

Typical repair vs replace cost logic

Use this simple rule: if the repair total is under 40% to 50% of the cost of a comparable replacement compressor, repair usually makes sense.

Situation	What it usually means	Best move
Won’t start, hums or trips breaker	Electrical/control issue or unloader/check valve issue	Repair first
Runs but won’t build tank pressure	Leak, valve, gasket, reed/valve plate issue	Diagnose, then repair if pump is otherwise healthy
Can’t adjust output pressure	Regulator issue	Repair
Tank won’t hold air	Leak at fittings or drain valve, or tank problem	Repair leaks; replace if tank is the issue

Why it matters

A targeted repair restores safe, reliable pressure control and prevents repeated cycling, overheating, and premature pump wear. Replacing a unit that only needs a control or leak fix often costs more than necessary.
