Stucchi VEP-HD Screw Flat Face Hydraulic Coupling Heavy Duty
Why You Should Be Using VEP-HD Couplers
Why You Should Be Using VEP-HD Couplers
If you're running high-impulse hydraulic attachments — whether it's rock breakers, augers, grabs, pulverisers, or rotating grapples — the Stucchi VEP-HD series is a game-changing upgrade. These flat face, screw-to-connect couplers are built to handle extreme backpressure, surge loads, and punishing duty cycles where standard push-to-connect or thread-on fittings simply don’t survive.
VEP-HD couplers deliver a rock-solid, leak-free connection that stays locked in under intense vibration and side load. No brinelling. No accidental disconnections. No struggling to connect under pressure. Whether you’re using hose-to-port threads or standard quick couplers, this is a serious step up in reliability, safety, and performance.
Ideal for demolition, civil construction, quarrying, forestry, and mobile plant, VEP-HD couplers have been tested to over 1 million impulse cycles at 133% working pressure — and they just keep going. From OEMs building hydraulic systems to operators in the field who can't afford downtime, Stucchi is the trusted choice.
Step up to VEP-HD.
No more smashed couplers. No more seized fittings. No more second-guessing your connections — just bulletproof performance, every time.
Choose the type, size, and thread style to suit your setup — BSPP, UNO (O-Ring), NPT, or Code 62 Flange. Don’t forget to add protective caps/plugs to keep your gear clean and damage-free.
