Product Overview

The PH01V00037R400 hydraulic cylinder seal kit is a rebuild set supplied by DJF Seals for the boom cylinders of New Holland, Kobelco and Case compact excavators. PH01V00037R400 is a genuine CNH part number — it is listed as “KIT, SEALS” in the official myCNHstore catalog for both CASE Construction and New Holland Construction, and by CNH dealers such as Clinton Tractor (CROP) as the seal kit for the New Holland E50B. The alternative number 72283999 is corroborated by Amazon and eBay listings. The kit covers the sealing elements of one boom cylinder — rod seals, piston seals, wipers, wear guidance components, backup rings and O-rings as applicable. DJF Seals supplies it factory-direct for heavy-equipment parts distributors, repair shops and fleet maintenance teams.

Verified Application

Boom cylinder of New Holland E50-series, Kobelco SK40SR-3 and Case CX50B compact excavators. Cross-verified sources: eBay lists “PH01V00037R400 Boom Cylinder Seal Kit For Kobelco SK40SR-3 Case CX50B New Holland E50/E50SR/E50BSR”; Amazon lists a “Boom Cylinder Seal Kit, Compatible with Kobelco Sk40sr-3, Ph01v00037r400 72283999”; Clinton Tractor (CROP) lists the genuine kit for the New Holland E50B. The official CNH catalog entry is “KIT, SEALS” and does not display fitments — the model matches above come from aftermarket and dealer listings. The page also mentions an arm-cylinder application, but no independent source was found for it (see Fitment Verification).

Replacement Scope

One boom-cylinder seal set per kit — rod and piston sealing elements with wipers and wear guidance components as supplied. The kit is referenced for the boom cylinder by all independent sources found. Confirm the model and the cylinder of your machine before purchase. No independent source publishes dimensions for this kit; do not assume rod or bore sizes.

Fitment Verification

Models verified across independent sources: New Holland E50, E50SR, E50BSR (eBay) and E50B (Clinton Tractor CROP); Kobelco SK40SR-3 (eBay, Amazon, FASeals); Case CX50B (eBay, Amazon). EH50.B appears on the page only — unverified. CONFLICT NOTE: the page lists “Boom Cylinder, Arm Cylinder”, but every third-party source found references only the boom cylinder — confirm the cylinder position before ordering. The page also contains a section headed “Compatible Models for part number 236-11516”; no independent source links 236-11516 to this kit (template artifact) — the verified alternative number is 72283999. Note that the official myCNHstore listing shows no fitments, so always double-check your machine serial and cylinder before purchase.

Factory Inspection & Packing

Every DJF seal kit is checked against its part number and application list before packing: seal elements are inspected for visible defects, counted against the kit list, and packed in sealed PE bags with a parts label. Kits are then packed into export cartons for warehouse or direct shipping. OEM/ODM branding and custom packaging are available on request.
