What is size and type of the banjo fittings on the cylinder? I would like to remove the lock valve and plumb directly.
A: The o.d. of the thread is .641" and it appears to have a thread per inch count of 19. It does not completely match any easily identifiable standard thread; either machine or hydraulic type.

Would this cylinder work with 1.5 cu in SA Wolverine WHP-15-SA Hand Pump Head ITEM NUMBER: 9-8436-15 Or would I need something else.
A: Because this cylinder is double-acting with a lock valve, it should not be used with a single-acting pump. A double acting hand pump such as 9-8437-15 or 9-8437-21 could be used if necessary.

I have one of these cylinders. The cross pipe hits part of my tractor and now its bent. I see you have repair kits but that will just get bent too. I would like to move the valve block away from the cylinder. Can you please list the parts needed to do this with hose from the cylinder to the valve block?
A: We do not have the parts needed to relocate the block in the fashion you describe, unfortunately.

It there a ball relief or ball check valve in the connector block ?. I need to carefully pull rocks from a garden plot using a scarifier. Tractor dealer said the top link would be the first point of failure if we strike a big one too hard. So a relief valve would be nice.
A: No that block is a lock valve which serves to hold the cylinder in place. Using only the control valve it is possible to have some drift, which this prevents.

I HAVE A MAHINDRA 2555 HST WITH PIONEER SYTLE FITTING HYDRAULICS. DOES THAT FIT THE NPTM OR BSPPM HOSES THAT COME WITH TOP LINK ITEM NUMBER 9-7682-11? IF NOT, WHAT ELSE WOULD I NEED TO GET TO MAKE IT WORK?
A: The Pioneer fitting should have a model number which may state the porting on the tip itself. If not then the manufacturer should detail the port on their website. Once you know the porting you can tell what, if any, adapter is necessary.

Your description says "Ships with two 3/8" BSPPM to 3/8" NPTM connectors". Does that mean if I buy a NPTM hose assembly I'll need a different connector to accept the male end of the hose?
A: Yes. If you buy male NPT hoses you will need fem/fem unions to join them (9-5000-6-6) or replace the supplied fittings with 9-8855-6-6 that are BSPP 3/8" male to 3/8" NPT female.
