got a line i need to cap off, is this the right one if my fitting is 5/16-24?

Answer by: Customer Support on Apr 21, 2025, 6:06 AM

The key callout on this cap is the 5/16-24 thread. If the port or fitting you are capping uses a 5/16-24 JIC 37 degree flare connection, this is the matching cap style.

Question by: Phil H on Nov 7, 2025, 6:18 PM

got a 5/16-24 JIC line I need to plug off on a hydraulic circuit, this cap gonna work for that?

Answer by: Customer Support on Nov 9, 2025, 6:45 AM

That's what this cap is built for. The 5/16-24 thread fits standard JIC fittings, and the 37-degree flare seat gives you a solid, leak-free seal on capped-off fluid lines. Steel construction holds up well in hydraulic system pressures and regular shop conditions.
