55K Direct Drive End Cap

An OEM end-cap or Flow Eagle-style 55,000 psi direct-drive pump assemblies. It supports the high-pressure cylinder and sealing stack at the end of the pump section, helping maintain proper alignment, compression, and containment during repeated pressure cycling. Replace the end cap when wear, corrosion, thread damage, cracking, or sealing-surface damage prevents reliable high-pressure operation.
