ST Shengtuo Valve Core for R410 R32 R22,High Pressure with

This valve core is a direct-replacement component for service ports on HVAC and refrigeration equipment where high-pressure performance and leak resistance are essential. Manufactured to meet demanding pressure requirements, the core uses a durable Teflon sealing surface to reduce leak paths and improve service life. Supplied in bulk, the 50-pack is aimed at technicians, contractors and facilities teams who need reliable spares for routine maintenance, repairs or new installations.

How does this valve core perform in high-pressure refrigeration systems?

The design targets systems that operate under elevated pressures such as R410A and R32, plus legacy R22 setups. The core body and sealing components are specified to handle sustained service pressures and repeated service cycles without deforming.

• Engineered for high-pressure refrigerants including R410, R32 and R22
• Robust metal body resists bending and wear during service
• Teflon seal reduces permeation and improves longevity
• Manufactured to consistent dimensional tolerances for reliable fit

Is the Teflon seal better than standard rubber seals?

Teflon (PTFE) offers chemical compatibility and a lower friction surface compared with many elastomer seals, which helps reduce leak risk and wear from repeated valve actuation. It is particularly useful with modern refrigerants and in systems where temperature swings and oil exposure could degrade rubber over time.

• Improved chemical resistance to refrigerants and lubricants
• Lower friction for smoother valve operation and less wear
• Stable across a wider temperature range than many elastomers
• Helps maintain a tighter seal under repeated service cycles

How easy is installation and compatibility with existing equipment?

These valve cores are designed to fit standard Schrader-style service ports used across a broad range of HVAC and refrigeration equipment, making them suitable for both commercial and residential applications. Installation requires common service tools and follows normal valve core replacement procedures.

• Fits standard Schrader-style service ports on most systems
• Installable with a standard valve-core tool or service wrench
• Bulk pack reduces downtime by keeping spares on hand
• Ideal for maintenance kits and service trucks

What does the pack of 50 mean for service and inventory?

A pack of 50 is aimed at professionals who replace valve cores frequently or manage multiple units. Keeping a bulk supply simplifies logistics, reduces per-piece cost, and ensures you have on-the-shelf parts for fast turnaround during routine maintenance or emergency repairs.

• Cost-effective bulk supply for frequent service tasks
• Reduces reordering frequency and downtime
• Useful for stocking service vans and facility maintenance stores
• Consistent parts across multiple jobs improve workflow

Who this is for: HVAC technicians, refrigeration service contractors, maintenance teams and facility managers who need a reliable, high-pressure valve core compatible with R410, R32 and R22 systems. If you keep service vans stocked, manage multiple HVAC units, or run scheduled preventive maintenance, this Teflon-sealed, pack-of-50 option provides dependable spare parts and lowers operational interruptions.
