Product Description

Pioneer 8200 Series Coupler - Female Thread | 8250-4

Parker's connect under pressure, agricultural quick couplers and nipples are the farmers choice where fluid lines require fast and easy connection and disconnection, featuring a sleeve designed to accommodate bracket/bulkhead mounting.

The 8200 Series unique valve design allows connection while either or both the coupler and nipple are under pressure. Valves in both halves remain closed, opening only when system pressure has been relieved on the female body and then reapplied. This pressure sequence may be done with either an open center or a closed center hydraulic system that has a control valve.

8200 Series Couplers (hydraulic) 3000 psi, connect with 8010 Series Nipples (ISO 5675, Pioneer male tips). Ball or poppet valve options.

Parker's 8200 Series are double shut-off, quick couplings that can connect under system pressure on the coupler side and residual pressure on the nipple side. The unique valve design allows connection while either or both the coupler and nipple are under pressure. Valves in both sides remain closed, opening only when system pressure has been relieved on the coupler body and then reapplied. This pressure sequence may be done with either an open center or a closed center hydraulic system that has a control valve.

Couplers have push to connect operation when the coupler is clamp or bracket / bulkhead mounted and are ideal for use in applications where a breakaway feature is desirable. Couplers are compatible with 5001-4 and 5006-4 breakaway clamps.
