Description & Features

The HK Series Industrial Interchange Series B Stainless Steel Hydraulic Quick Disconnect offers reliable performance across various applications including agriculture, construction, transportation, and oil and gas. Engineered with stainless steel construction, this coupling provides superior corrosion resistance and fluid compatibility.

Designed to conform dimensionally to ISO standard 7241/1 Series B, it features a self-sealing poppet valve design for both high and low-pressure sealing. The Push-to-Connect mechanism facilitates quick and secure attachment, making it highly functional in demanding environments.

Operating efficiently between temperatures of -40deg;F to +250deg;F with Buna-N seals, this hydraulic quick disconnect ensures minimal fluid loss at 0.90 cubic centimeters and air inclusion max at 1.20 cubic centimeters. Its 1/4-18 Female NPT threading and standard body material contribute to its durability and lasting performance.

The absence of a safety locking mechanism and the use of stainless steel in its construction elevate its utility in industries like chemical, military, and medical among others.

Question by: Floyd H on Mar 1, 2026, 8:17 AM
Will this quick disconnect work with other brands that meet the ISO 7241/1 Series B standard?
Answer by: Customer Support on Mar 2, 2026, 11:18 AM
Because it is an industrial interchange coupling conforming dimensionally to ISO standard 7241/1 Series B, this should work fine with other brands that also meet that spec.
Question by: Bobby J on May 11, 2025, 2:46 PM
Trying to replace an old Series B style plug, is this one the stainless male half with a 1/4-18 female NPT port?
Answer by: Customer Support on May 13, 2025, 6:11 AM
It matches the Industrial Interchange ISO 7241/1 Series B style and it is the male half. The threaded end is 1/4-18 female NPT and the coupling size is -04.
Question by: Jerry F on May 6, 2025, 2:20 PM
What kind of seal comes standard on this coupling, and how cold can it actually get before that seal starts giving trouble?
Answer by: Customer Support on May 8, 2025, 11:21 AM
Buna-N is the standard seal material on this one. It holds up from -40 degrees F all the way up to 250 degrees F, so if you're running equipment through hard winters or in heated fluid applications, you've got solid coverage on both ends of that range. If your setup pushes past 250 degrees, there are other seal options available for this series, including EPDM rated to 300 degrees and FKM rated to 400 degrees, so the platform gives you room to spec it correctly for hotter conditions.
Question by: Keith J on Jul 8, 2025, 9:12 AM
Just wanna make sure, this is stainless steel, right? I'm dealing with some harsh chemicals.
Answer by: Customer Support on Jul 10, 2025, 6:35 AM
Yes, the body material is stainless steel, which gives you greater corrosion resistance and fluid compatibility.
