What Should I Check Before Ordering a Female-Thread Coupler?

Start with the CEJN part number if it is available. Then confirm the thread standard, thread size, quick disconnect series, pressure rating, and mating component. NPT, BSPP, and Rc/BSPT connections use different thread standards, so a matching nominal size does not automatically mean the coupler is suitable for the same connection.

Are All CEJN Female-Thread Couplers Rated for the Same Pressure?

No. Pressure ratings differ by model and series. The live category includes products rated at 232 PSI as well as high-pressure models listed at 10,153 PSI, 11,600 PSI, 14,500 PSI, and 21,756 PSI. Always use the individual product specification rather than applying one pressure rating across the category.

How Can I Identify the Correct Replacement Coupler?

Part numbers are usually the fastest way to identify the exact replacement. If the original number is unavailable, record the female thread type and size, series, pressure requirement, and details of the mating nipple. G&G Hydraulics Corporation can help compare those specifications and narrow down the correct female thread coupling option.

Compare Thread Type, Series, and Pressure Rating

Selecting a female thread coupling starts with the connection standard and operating requirements. The current category includes NPT female threads in 1/8-inch, 1/4-inch, 3/8-inch, and 1/2-inch sizes, along with BSPP female-thread options and a 1/4-inch Rc/BSPT female-thread option. Available CEJN series include 115, 116, 232, 310, 320, and 410.

Pressure ratings vary substantially by series. For example, CEJN 10-310-1402 is a 1/4-inch NPT female-thread quick disconnect coupler rated at 232 PSI, while 10-116-1402 uses a 1/4-inch NPT female thread and is rated at 21,756 PSI. Other models include 10-115-1401 with a 1/8-inch NPT female thread and a 14,500 PSI rating. Check the exact part number, thread standard, size, series, and pressure rating before ordering. This comparison is especially important when similar couplers share a size but differ in pressure capability.
