Swagelok JC1667PL25 Solid Stainless Steel End Cap

Swagelok JC1667PL25 is a solid stainless steel end cap from the JC16 family, sized for a 2-1/2 in (63.5 mm) outer-diameter end connection used with Swagelok tubing fittings. JC16 solid end caps cover sizes from 1/2 in to 6 in, and the JC1667PL25 designation denotes the 2-1/2 in option with the PL finish, with additional finishes such as PM and Standard also available. The PL suffix identifies a JC16 finish variant within the lineup, and these end caps are designed to seal unused ends to protect the system from contaminants and mechanical damage during maintenance or downtime. Swagelok end caps, including this solid stainless steel model, are used to keep tubing and cylinder neck connections clean when not in use, preventing debris ingress and preserving system integrity.
