Jsyfcfc ECX5000G Diaphragm Gasket & ECX1014A Bump Shaft Kit for D–E Filters — VMQ/EPDM Upgrade, Complete Seal Repair

Jsyfcfc ECX5000G diaphragm gasket and ECX1014A bump shaft kit are replacement components designed to restore sealing and actuation performance in EC30, EC40AC, EC50A and EC50AC series D–E pool filters.

When a filter’s diaphragm or bump shaft wears out, leaks, reduced backwash action, or noisy operation can follow. This kit combines a VMQ diaphragm gasket and upgraded EPDM/VMQ bump shaft components to replace the original D–E filter parts and return reliable operation without replacing the entire valve assembly. The set includes the diaphragm gasket plus washers, O-rings and retainers needed for a direct swap—confirm your filter model before ordering.

How will this kit affect my filter’s sealing and backwash action?

The new diaphragm gasket re-establishes a tight seal between valve body sections and the bump shaft assembly ensures consistent movement during backwash cycles. Improved elasticity and material stability reduce the chance of deformation under heat or chemical exposure.

• VMQ diaphragm gasket resists aging and retains elasticity.
• EPDM/VMQ components maintain sealing under pool chemicals.
• Includes O-rings and retainers for a complete seal refresh.

Which models are compatible and what parts come in the kit?

This replacement is made for EC30, EC40AC, EC50A and EC50AC series extended D–E filters—verify your model number to ensure fit. The kit supplies the primary diaphragm gasket plus the smaller fasteners and seals needed for installation so you can replace the worn parts in one service visit.

• ECX5000G Diaphragm Gasket ×1 for the valve diaphragm sealing surface.
• ECX1011 Washers ×2, ECX9611246 O-rings ×3, ECX1014 Retainers ×2.
• Alternate references include HAY-051-1507, EC-50C, EC-40C for cross-checking.

What materials and durability improvements should I expect?

This kit upgrades several parts to VMQ (silicone) and EPDM elastomers that better resist high temperatures, chemical exposure and mechanical fatigue. Those material choices slow hardening and cracking so components keep working longer than many original rubber parts.

• VMQ offers high elasticity and temperature tolerance for the diaphragm.
• EPDM parts resist common pool chemicals and ozone-related aging.
• Combined materials reduce the frequency of service replacements.

How difficult is installation and what tools will I need?

Installation is intended as a straightforward replacement of the original ECX5000G and ECX1014A parts—no major modifications required. Most experienced DIYers or pool technicians can complete the swap using basic hand tools and standard safety precautions.

• Remove the old diaphragm and bump shaft components from the valve body.
• Clean mating surfaces, install supplied O-rings, washers and retainers.
• Reassemble and test through a manual backwash or system run to confirm sealing.

Who is this for: This Jsyfcfc kit is aimed at pool owners, maintenance technicians, and service shops who want a reliable, materials-upgraded replacement for worn D–E filter valve components without purchasing a full valve assembly. Choose this kit if you have an EC30, EC40AC, EC50A or EC50AC series D–E filter and need a complete diaphragm-and-bump-shaft refresh that includes the necessary seals and retainers for a proper repair.
