The Parker 901GH‑12 rubber hose washer will be obsolete and replaced by the new 30GH‑12 seal.
Garden Hose Washer Change Overview
- 80 durometer EPDM 901GH‑12 washer is replaced by the softer 70 durometer EPDM compound in the 30GH‑12 washer.
- The softer material promotes superior compression and better surface contact during installation, making it more forgiving if the mating surface is slightly irregular.
- Integrated retention tabs ensure the seal remains positioned during shipping and installation—a feature engineered to minimize handling errors and reduce assembly defects.
Benefits of the Softer 30GH-12 Garden Hose Washer
- Enhanced Leak Prevention – The 70 durometer EPDM in 30GH‑12 compresses more readily, increasing contact sealing pressure and reducing micro-gap formation under load.
- Installation Reliability – Tabs embedded in the seal design help the washer stay correctly seated even during transport or handling, improving assembly quality control.
- Broader Application Compatibility – The dual-use design means the seal is suitable in both stand‑alone and integrated fitting assemblies, offering flexibility for customers who standardize across multiple configurations.
Implementation Plan & Timeline
- Discontinue shipments of the 901GH‑12 once the current inventory is depleted.
- Begin shipping the 30GH‑12 seal for all new orders and whenever replacement washers are specified.
- Update documentation (e.g. drawing BOMs, installation guides, ERP systems) to reflect the 30GH-12 part number across both independent and dependent assembly references.
- Support transition with our customer service, ensuring clear part cross-referencing during the overlap period.
What You Should Know
- Form, Fit & Function – The 30GH‑12 garden hose washer retains the same basic form and fit as the 901GH‑12. Thread size, outer diameter, thickness, and installation footprint remain the same.
- Material Change Notice – The only difference is in EPDM hardness, which has changed from 80 durometer (firmer) to 70 durometer (softer). This change is implemented to support superior sealing reliability.
- Backward Compatibility – The new seal is fully compatible with existing Parker fittings that were previously paired with 901GH‑12.
- Operational Assurance – The new 30GH‑12 hose washer has been tested to Parker’s engineering standards for typical garden hose applications, and continues to meet the same up to 150 psi pressure rating and temperature range via EPDM’s broad operational resilience
Final Notes
Parker and Western Integrated Technologies are committed to continuous quality improvements. The transition from 901GH‑12 to 30GH‑12 reflects our proactive efforts to enhance product performance and reliability—especially preventing leaks, which can result in downtime and customer dissatisfaction.
