Question by: Neil J on Dec 28, 2025, 7:57 PM

got a rig that runs pretty hot sometimes. what kinda temps can the seals on these test fittings handle

Answer by: Customer Support on Dec 30, 2025, 2:23 PM

Depending on the exact seal material you choose, the heat tolerance varies. Viton seals give you the highest rating from -4 to 392 degrees Fahrenheit. Buna-N handles up to 195 degrees and EPDM is rated for up to 302 degrees.

got a gauge and a little test hose setup, what’s this SMK-20-JIC3/8-V-K-W3 actually meant to do?

Answer by: Customer Support on Jul 29, 2025, 6:46 PM

Built for pressure test work, it’s used for monitoring and control of pressure, plus venting and sampling in hydraulic systems. It’s meant to let you hook up measurement, control, and switching devices while keeping the connection leakproof before the connection is opened.

Question by: Freddie B on Mar 16, 2026, 8:58 AM

what's the pressure rating on this test hose, and can it handle live connections without shutting the system down?

Answer by: Customer Support on Mar 17, 2026, 9:05 PM

Rated for a maximum working pressure of 5800 PSI, the SMK-20 series hose also supports connection under pressure up to 5800 PSI. That means you can hook up your gauges or monitoring equipment while the system is running without needing to depressurize first. The connection stays leakproof before it opens, so you're not spilling fluid or introducing air during the swap.

Question by: Shawn R on Jan 29, 2026, 2:49 PM

What kind of fluids can I run through this thing?

Answer by: Customer Support on Jan 31, 2026, 6:07 AM

This test point is suitable for hydraulic oils and other mineral-based fluids, but you'll want to double-check the seal material compatibility first. If you're thinking about using it with something other than typical hydraulic fluids, it's best to call and confirm the availability of alternate seals.
