{"product_id":"5j-3620-rod-buffer-seal","title":"5J-3620 Rod Buffer Seal For Caterpillar | Ruijueparts","description":"\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003e5J-3620 is an aftermarket rod buffer seal for matched Caterpillar hydraulic cylinders. Its role differs from the primary rod seal: it helps shield that seal from pressure changes during cylinder operation. Check the gland arrangement and original reference before selecting an individual ring. A shared rod diameter does not establish interchangeability with 5J-0964. Ruijueparts can review the cylinder number and repair list so a workshop orders the correct sealing position rather than a visually similar part.\u003c\/p\u003e\u003ch2\u003eItem specifics\u003c\/h2\u003e\u003cp\u003ePart Number \/ Ordering Reference: 5J-3620\u003c\/p\u003e\u003cp\u003eCompatible Brand: Caterpillar\u003c\/p\u003e\u003cp\u003eType: Rod Buffer Seal\u003c\/p\u003e\u003cp\u003eCondition: New\u003c\/p\u003e\u003cp\u003eManufacturer Type: Aftermarket\u003c\/p\u003e\u003ch3\u003eApplication\u003c\/h3\u003e\u003cp\u003eTrack Loader: 943 \/ 953 \/ 973.
