Febco PVB Bonnet & Poppet Repair Kit 1"–1-1/4" — Complete OEM Parts for #765

Febco FE905-212 is a complete bonnet and poppet repair kit built to restore 1" and 1-1/4" pressure vacuum breakers quickly and reliably.

This replacement kit supplies the internal components needed to service Febco #765 and compatible pressure vacuum breakers without replacing the entire assembly. It gathers the bonnet, poppet, stem, rubber disc and all small hardware into a single package so you can return a leaky or malfunctioning unit to service with factory-fit parts. The parts are made to match the original geometry so fit and function are preserved during maintenance.

What parts are included and why does each matter?

The FE905-212 kit contains every internal part you normally need when repairing the bonnet and poppet assembly on 1"–1-1/4" pressure vacuum breakers. Replacing worn internal parts prevents leaking and ensures correct pressure and flow behavior.

• Bonnet — restores the housing that secures internal components.
• Poppet and rubber disc — re-establish a tight seal at the waterway.
• Stem, spring, washer, E-ring and O-ring — ensure correct movement and sealing under pressure.

How easy is installation for a field repair?

Designed for field servicing, the kit’s parts are straightforward to install and don’t require specialized tools beyond common hand tools used for valve maintenance. Clear access to the bonnet area on standard PVB designs means most technicians can complete the job during a routine service call.

• No special tooling required — uses standard hand tools.
• Direct-fit components — reduces trial-and-error in assembly.
• Compact kit organization — all parts provided so you won’t need multiple orders.

Will these parts restore original performance and durability?

Using original-equipment parts helps recover original sealing and mechanical action. Materials and tolerances are matched to the factory specification so the repaired valve behaves like the original installation when correctly assembled.

• Factory-match parts maintain designed clearances and spring tension.
• Durable elastomers and metals resist typical wear from cycling and water exposure.
• Replacing worn internal parts reduces the risk of operational failures and water loss.

Which valve models and sizes does this kit fit?

This FE905-212 bonnet/poppet repair kit is engineered for 1" and 1-1/4" pressure vacuum breakers, including Febco #765 series and other valves built to the same internal geometry. Confirm size and model compatibility before ordering to ensure correct fit.

• Fits Febco #765 1" and 1-1/4" PVBs.
• Compatible with valves sharing the same bonnet/poppet arrangement and dimensions.
• Check valve body size stamping or model tag for confirmation.

Who this is for: This kit is intended for plumbing professionals, irrigation technicians, and maintenance teams who want a serviceable, cost-effective alternative to full valve replacement. It’s ideal for routine maintenance, emergency repairs, and keeping commercial or residential backflow protection devices operating within specification. If you service 1"–1-1/4" pressure vacuum breakers and need an OEM-style parts package to restore seal integrity and mechanical action, the Febco FE905-212 provides the essential components in one purchase.
