ENGINE TEST EQUIPMENT
H1730
Replacement Valve Cores
Most Compression tester failures are due to worn or dirty
valve cores. DO NOT REPLACE WITH TIRE VALVE CORES,
as incorrect reading will result. Valve cores for all JET
Compression Tester:
H1734K Package of six ( H1726, 30, 31, H3041)
H1845G Diesel Tester ( H1845)
H1730 LE*
COMPRESSION TESTER
WITH QUICK DISCONNECT FLEXIBLE HOSE
• The most popular type in use today
• The heavy duty neoprene hose bends in all directions to reach hard to get at cylinders
• Handy side release valve allows multiple readings on the same cylinder without removing the
tester from the cylinder
• Hose assembly will disconnect easily from the gauge head to allow more flexibility
and easier installation into spark plug holes
Replacement Parts:

ENGINE TEST EQUIPMENT
H3042 Y
CYLINDER LEAK DOWN TESTER
• Tests for worn or broken rings, defective intake and exhaust valves, scored or cracked cylinders,
leaky head gaskets and worn or stripped spark plug threads by measuring the amount of
compressed air held in an engine cylinder
• Easy to use on all 2 and 4 cycle gasoline and diesel engines
• Dual gauges allow you to monitor input air line pressure up to 100 psi
• Unit has precision pressure regulator to adjust pressure in cylinder to “set” area on
regulator gauge
• Regulator gauge will read percentage of leak down in cylinder while the input pressure gauge
assures that input pressure is steady
Replacement Parts:
H3042A Y Gauge Head
H3042B Regulator
H3042C Y Leakage Gauge
H3042D Hose Assembly - 11-1/4" with 14 & 18mm Adaptors,

H1730F Adaptor 12mm
H1730H Adaptor 16mm Ford Triton Engines
H3042K Diesel Adaptor Hose - 15-1/2"
• Use of this hose allows the tester to be used on diesel engines with adaptors
H1343 LE*
HIGH PRESSURE & VACUUM TESTER
• Higher operating pressures require a larger capacity pressure gauge to test the system
• Test for fuel line pressure & vacuum leaks. Check for leaky valves, timing, fuel pump vacuum,
pressure and more
• Dual scale, easy to read dial with heavy duty gauge movement
• Hose length: 36-1/2"
Pressure Range: 0-60 psi, 0-4 kg/cm 2
Vacuum Range: 0-30 in., 0-76 cm HG
