Description
When your oil pressure gauge starts reading erratic or you’ve noticed oil weeping around engine fittings, there’s a good chance one of your oil pressure pipe unions has given up the ghost. These small but critical fittings connect your engine’s oil pressure sensing line to the gauge, and when they fail, you lose the early warning system that keeps expensive engine damage at bay.
What You’re Getting
- Precision-threaded union that seals tight and stays sealed through years of engine vibration
- Pack of 2 unions so you’ll have a spare when you need it most
- Direct replacement design that threads right into your existing oil pressure line setup
- Quality brass or steel construction that handles the constant pressure cycling
- Proper bore size maintains accurate pressure readings to your gauge
Built for Real Farm Work
This union fits the classic Massey Ferguson workhorses that built modern farming – the reliable TE20, the versatile 35 series, and the legendary 135. These tractors are still working farms today because they were built right, and they deserve quality parts that maintain their reputation for dependability.
Made to Last
Oil pressure fittings might seem simple, but they’re under constant pressure and vibration. These unions use quality materials and proper thread pitch to seal correctly without over-tightening. The smooth bore design won’t restrict flow or create false pressure readings that could mask real engine problems.
Good to Know
When replacing these unions, clean the threads thoroughly and use a pipe thread compound – not tape, which can shred and clog oil passages. Thread them in hand-tight plus one turn with a wrench. Over-tightening actually makes leaks more likely by distorting the threads. Check your oil pressure gauge operation after installation to make sure you’re getting accurate readings.
