Boltigen HVAC Access Service Valves 30-Pack — 1/4" SAE x 1/4" OD, 3.54" Stem, Brass/Copper Spring-Core

These service valves are designed for technicians and installers who need dependable, corrosion-resistant access points for refrigerant systems. Each valve includes a threaded, spring-loaded core that opens to allow gas flow when engaged and reseals tightly when released. The set of 30 gives you enough spares to service multiple units or keep on-hand for field repairs, and every valve ships with removable caps and a core remover for fast maintenance.

How do these valves simplify charging and pressure testing?

The Boltigen access valve provides a sealed, threaded port engineered for easy attachment of gauges, hoses and charging tools without refrigerant loss. The internal poppet core is spring-assisted to minimize leakage during connection and disconnection.

• 1/4" SAE inlet and 1/4" OD stem compatible with common HVAC hoses and fittings.
• Spring-loaded core reduces refrigerant venting during tool hookups.
• Removable cap and included core remover speed routine service tasks.
• Pack of 30 supplies multiple units and spare replacements.

What materials and build features affect durability?

These valves are crafted from corrosion-resistant metal alloy to withstand harsh refrigerants and typical environmental moisture encountered in HVAC applications. The robust stem and threaded body resist wear from repeated connections and the integrated core is designed for consistent resealing.

• Brass/copper construction for oxidation resistance and long service life.
• Threaded design keeps the core firmly seated under pressure.
• Self-contained stem valve avoids external seals that can leak.
• Durable caps protect the port between uses.

Can these valves be used with bullet-piercing fittings and various refrigerants?

Yes — the Boltigen access valves are commonly used alongside piercing fittings when installers need a more permanent or serviceable access point. They work for vacuuming, charging and pressure measurement on many refrigeration and air conditioning systems; confirm compatibility with specific refrigerants and system requirements before use.

• Compatible with standard HVAC service tools and gauges.
• Intended for vacuum pull-downs, charging and pressure diagnostics.
• Use with bullet-piercing fittings when converting a pierced line to a serviceable port.
• Verify refrigerant type and system pressure ratings prior to application.

What warranty and support are included?

Boltigen provides a limited one-year warranty covering manufacturing defects to give technicians confidence in field use. If you encounter a functional issue, Boltigen's support can assist with replacement or troubleshooting for products within the warranty period.

• One-year limited warranty for manufacturing defects.
• Customer support available for installation or product concerns.
• Packaged set of 30 valves reduces downtime from shortages.
