Product questions
What thread and body size does the SM-502-8FP nipple have?
It has a 1/2-inch coupling body and a 1/2-14 female NPTF port. The quick-connect nipple is the male coupling half; the threaded port is female. Its catalog length is 2.01 inches.
What pressure rating should I use for SM-502-8FP?
Parker catalogs give conflicting ratings: the SM Series table lists 6,000 psi for a 1/2-inch body, while the Pioneer original equipment table lists this exact part at 3,000 psi. Confirm the applicable rating for the supplied part and complete coupling before selection; do not assume the higher figure.
Will SM-502-8FP fit my Allis-Chalmers hydraulic coupling?
A Parker Pioneer catalog identifies this nipple with an old-style Allis-Chalmers application and lists a connection to the 255018 coupler. That does not establish fit for every machine. Provide the equipment model and serial number and the existing coupler identification for verification.
What flow and seal material are specified for this nipple?
The 1/2-inch SM Series is cataloged at a rated flow of 12 US gallons per minute with standard nitrile seals. Confirm seal suitability for the hydraulic fluid and operating temperature before ordering.
