FAQ

Q: What types of gas canister connections are supported by these adapters?

A: We manufacture multiple configurations supporting conversions between EN417 screw-type (Lindal valve), bayonet-type, and piercing-type canisters depending on the specific model requirement.

Q: Does the adapter feature an automatic gas shut-off mechanism?

A: Yes. The internal valve structure incorporates a spring-loaded check pin that seals the gas passage automatically the moment the appliance or canister is unscrewed.

Q: What materials are used to prevent gas leakage at low temperatures?

A: We utilize high-elasticity FKM or cold-resistant NBR O-rings combined with precision-machined sealing grooves to maintain tight sealing down to minus 20 degrees Celsius.

Q: What is the standard minimum order quantity (MOQ) for custom OEM orders?

A: The standard MOQ for custom laser branding and anodized color variations is 2,000 units per specification. Smaller quantities for neutral stock items can be reviewed case by case.

Q: What quality assurance documentation is provided with bulk shipments?

A: Each shipment includes raw material inspection reports, thread gauge verification logs, 100% pressure test certificates, and standard packing lists.

Q: What is the typical lead time for production and delivery?

A: Standard production lead time requires 20 to 30 days following sample confirmation and order deposit receipt, subject to total order volume and custom tooling requirements.
