Description
Overview:
The Seal Washer Dowty 1/2 is a genuine Atlas Copco hydraulic sealing washer designed to stop leaks at threaded joints on power packs and associated tools. It is a metal washer with a bonded elastomer sealing lip that compresses to form a tight, reliable seal under pressure. Sized for 1/2 in BSP fittings (typical mating thread outside diameter around 21 mm), it supports secure, repeatable assembly without excessive torque. Built for demanding site conditions, it suits hydraulic circuits on equipment such as the Atlas Copco LP 9-20 and LP9-20 power packs, helping maintain system integrity, efficiency and uptime. Part number: 0661 1000 39. Genuine Atlas Copco part for assured fit and performance.
Key Features:
- Genuine Atlas Copco part for the correct fit and dependable sealing on compatible equipment
- 1/2 in BSP size (approx. 21 mm OD on mating BSPP threads) for common hydraulic connections
- Metal body with a bonded elastomer lip to prevent fluid bypass at flat-faced joints
- Helps stop weeping and full leaks on straight-thread and banjo-type fittings
- Robust construction for use in high-vibration, high-pressure hydraulic environments
- Simple to install; no special tools required beyond standard hydraulic assembly practice
- Can often be re-used if undamaged and correctly inspected after removal
- Suitable for typical mineral-based hydraulic fluids used in construction and plant equipment
Typical Applications:
Used at hose ends, pump ports, valve blocks, manifolds and plug interfaces where a 1/2 in BSP joint needs a reliable face seal. Ideal for power packs, breakers, compactors and other hydraulic tools in construction, utilities, hire fleets and workshop maintenance. Helps maintain pressure, reduce downtime from leaks and protect components from contamination caused by fluid escape.
