Question by: Travis S on Nov 19, 2025, 8:30 AM

got a pressure test port that needs venting and sampling too. is this SMK20 setup meant for that kind of work?

Answer by: Customer Support on Nov 20, 2025, 11:30 AM

For pressure monitoring and control tasks, this test system is intended for venting and sampling as well, so it fits that kind of day to day hydraulic troubleshooting and checks.

Question by: Danny H on Nov 30, 2025, 12:33 PM

what seals come on this thing, and are they gonna hold up in a system running straight hydraulic oil?

Answer by: Customer Support on Dec 2, 2025, 6:43 AM

Three seal options are available depending on your temperature needs. Buna-N covers the range of -4°F to 195°F, Viton runs from -4°F up to 392°F, and EPDM handles -40°F to 302°F. All three are listed as compatible with hydraulic oils and mineral-based fluids, so any of those seal materials should hold up fine in a standard hydraulic oil system. If you're running something outside that fluid type, you'd want to verify compatibility before committing.

Question by: Brett G on Jan 10, 2026, 6:36 PM

What kind of fluids can I run through this test hose?

Answer by: Customer Support on Jan 12, 2026, 6:14 AM

It’s suitable for hydraulic oils and other mineral-based fluids. Just be sure to check the seal material compatibility beforehand. If you’re thinkin' about usin' somethin' else, best give us a call to check on alternate seals.

got a gauge kit and need a test hose that’ll hook up without leaking all over. what’s this one meant to do

Answer by: Customer Support on Feb 6, 2026, 9:52 AM

For pressure monitoring and control work, plus venting and sampling, it gives you a leakproof connection before the connection is opened, so you can tie into measurement, control, and switching devices with less mess and less risk of pulling contamination into the system.
