Is the VKA Cap, Carbon Steel compatible with both L (light) and S (heavy) series for different pressure ranges?

Yes. VKA Cap, Carbon Steel Format is available in both L (light) and S (heavy) series, making it compatible with different pressure ranges and installation requirements. The 24° cone design and NBR O-ring ensure secure sealing, while the DIN 2353 compatibility with nut type M allows use across hydraulic and pneumatic systems. Carbon steel construction with a galvanized finish provides corrosion and wear resistance suitable for demanding conditions.

Does the VKA Cap, Carbon Steel require a specific torque when installed to ensure the NBR O-ring seals properly without damage?

VKA Cap, Carbon Steel Format does not specify a single universal torque value in the provided description. Proper sealing of the 24° cone with the NBR O-ring depends on correct tightening to compress the O-ring enough to seal without over-compressing or damaging it. Recommended practice: - Follow the assembly torque specified by the equipment manufacturer or the DIN 2353 system/adapter maker for the matching nut and tube size. - If no specific torque is available, tighten progressively by hand and then with a wrench until firm contact is achieved and a slight additional turn (usually 1/6 to 1/4 turn) — avoiding excessive force that can cut or extrude the NBR O-ring. - Use the correct series (L or S) matched to the pressure rating and tubing size; heavier series may tolerate higher tightening. - Inspect the O-ring after initial pressure testing for deformation or damage and retorque if leakage appears, using small incremental turns. - When critical, measure clamp torque with a torque wrench or consult supplier datasheets for torque tables corresponding to thread size and material. If you provide the thread/tube size and system pressure, I can suggest a tighter torque range or point to typical DIN 2353 torque tables.
