About the Rectus Regional Competence Center
HSI Holger Schmidt Industrietechnik GmbH & Co. KG operates the Rectus Regional Competence Center in Villmar (Hesse) and distributes quick-release coupling systems from the Rectus, TEMA and Parker brands for low, medium and high-pressure applications. The product range includes single-shut-off and double-shut-off couplings, low-leakage versions, safety couplings with automatic venting, breathing air couplings, plastic couplings in PVDF and POM, coded systems as well as couplings for mold cooling (KEEPCool). In addition, valves, hoses, blow guns and accessories are offered, along with tailored customer solutions and sample shipments. HSI GmbH & Co. KG has been working with Rectus GmbH for over 25 years; Rectus has belonged to the Parker Group since 2007, whose Quick Couplings Division Europe is based in Nussdorf. The company supplies customers in aerospace, maritime/offshore, automotive engineering, manufacturing, pharmaceutical and food industries, chemicals, as well as pneumatics and hydraulics.

Materials & Product Lines
Brass
Standard material for single-shut-off and double-shut-off couplings, often nickel-plated.
Stainless steel
For corrosion-prone applications as well as low-leakage coupling series.
Steel
Used for coupling bodies and galvanized plugs.
Aluminium
Anodized aluminium bodies for lightweight, robust safety venting couplings.
PVDF (polyvinylidene fluoride)
Chemically resistant plastic for couplings with corrosive media.
POM (polyoxymethylene/polyacetal)
Plastic for couplings, also available according to USP Class VI.
PSU (polysulfone)
Plastic according to USP Class VI for pharmaceutical and medical applications.
NBR (seal)
Standard sealing material in the coupling systems.
