Tee Fitting - Force - 20.042 — a direct-fit replacement hydraulic fitting. Ordering the hydraulic fitting from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same. Specifications Part number: ALS-7240-37 Type: Genuine OEM hydraulic fitting The cylinder is where hydraulic pressure becomes lift. Fluid pushed behind the piston drives the rod out, the rod raises the carriage or pulls the cables, and a check valve holds it up there until the lowering valve lets it back down. It's a simple, rugged part — until the rod seal wears or the barrel scores, at which point it can't hold pressure and the lift won't stay up. A hydraulic lift that won't hold height is telling you something before it fails outright. Drift-down, a spongy feel, milky fluid — these are early warnings, and the cheap fix is now. Ignore them and a weeping seal becomes a scored barrel becomes a whole cylinder; a tired pump becomes a burned-up motor. Worse, a lift that sags under load is a safety problem, not just a maintenance one. Related parts for this lift The parts below are commonly ordered alongside this one — cables, sheaves, seals, and hardware wear on similar schedules, and most repairs go faster when the whole set is done in one visit. Banjo Fitting - Force - 20.034 Replacing your hydraulic fitting Most hydraulic repairs share the same discipline: relieve pressure, keep the system clean, replace the part, then bleed the air and verify the lift holds under load. Contaminated fluid or trapped air will undo an otherwise good job. Because these parts keep a vehicle safely in the air, the full procedure is worth following start to finish. Full step-by-step: how to replace a car lift hydraulic hose. Find the right part for your lift If you are not sure this part matches your setup, the fastest check is the visual breakdown: open our parts lookup, pick your model, and match your part against the drawing where every item is numbered. Can't read the model plate? our guide to finding your model number shows exactly where it lives on each lift type, and we are a phone call away if you would rather have us confirm it. Signs of a hydraulic problem Fittings and washers are small but leak often. Check every copper washer on a bleeder or banjo for crush and flattening, every o-ring boss for a weep, and every flare for a hairline crack at the cone. A fitting that keeps weeping after you snug it usually needs a fresh washer or o-ring, not more torque — over-tightening cracks the flare and makes it worse. Parts commonly replaced at the same time A hydraulic repair is the right moment to handle the parts that fail alongside this one — seals, o-rings, the hose that feeds it, and fresh oil for the refill. Opening the system twice for parts you could have done together is wasted labor. We will build the seal-and-hose kit for your lift so the repair is complete in one go. Hydraulic fluid When you refill, use the right oil: ISO-32 hydraulic fluid on most lifts, or Dexron ATF on some older designs — never a blend of the two. Your installation manual lists the correct capacity for your specific lift, so fill to that spec and re-check the level after you have cycled and bled the system. Safety notes Hydraulic parts hold a vehicle in the air on pressure and a column of oil — respect both. Relieve system pressure before you crack any fitting, cap every open port so grit stays out, and bleed the system fully before the lift carries a load. Air in the lines is what causes a lift to drift or drop unexpectedly. Before you order Have the data plate in front of you when you order — model, serial, and voltage if it is a power unit. Match hose length and fitting type against the old part, and remember the job includes fresh oil and a full bleed. Not sure whether you need the part or just seals? Call and we will sort it. Not sure this fits? Here's how to check Pull the number off your lift's model plate first — model and serial both. Manufacturers run mid-cycle revisions that keep the model name but change hardware, so two lifts with the same name on the column can take different parts. The serial is what removes the guesswork. Second check: compare the old part against this listing before you order. Length, mounting pattern, and thread sizes tell most of the story. If anything doesn't line up, or if the old part is too worn or broken to measure, call us with photos — we work on these lifts every week and can usually confirm fit from a picture and the lift's serial faster than you can dig through a parts diagram.
