Featuring a PTFE/Neoprene seal, it withstands pressures up to 800 psi and temperatures from -40°F to 250°F. Manufactured with a high-copper brass alloy for corrosion resistance, it supports all refrigerants including R-410A, ensuring reliable, leak-proof performance backed by over 40 years of JB Industries’ trusted craftsmanship. ## Description JB machines all of the access valves at the factory in Aurora, Illinois using the highest level of brass consisting of 65% copper and 35% zinc. This gives our brass fittings and access valves high tensile strength while resisting corrosion. Many import fittings use lower quality brass with lower copper content, resulting in higher failure rates. JB machines all of our valves to the strict guidelines of the ARI to ensure proper sealing of the valve and core surfaces. Our access fittings have generous counter bores to allow for the removal of the core if the flare becomes damaged. All tees and crosses are tapped to receive an access core in all 1/4" SAE flare ends. All pipe connections have internal braze cups for dip tube applications. All valves are equipped with cap and one valve core (braze type, loosely assembled). Temperature range -40 degrees to +250 degrees Fahrenheit (-40 to 121.1 degrees Celsius). Valve core is stainless steel and brass for use with all refrigerants including R-410A. Resistant to oils, alkylates and diluted mineral acids. ## Features - PTFE/Neoprene seal replacement valve core - Max 800 psi and 220 degrees Fahrenheit (104 degrees Celsius) - For over 40 years, JB has been committed to producing products of the highest quality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E1NKERG | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #1,486,130 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #166,871 in Power Tool Parts & Accessories | | Brand | BBK | | Customer Reviews | 5.0 5.0 out of 5 stars (3) | | Date First Available | July 19, 2013 | | Exterior Finish | Brass, Stainless Steel | | Global Trade Identification Number | 00684520319998 | | Inlet Connection Type | Flare | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 0.32 ounces | | Item dimensions L x W x H | 2 x 2 x 2.5 inches | | Item model number | A31999 | | Manufacturer | Standard Plumbing Supply | | Material | Brass | | Maximum Operating Pressure | 800 Pound per Square Inch | | Number Of Pieces | 5 | | Number of Ports | 3 | | Outlet Connection Type | Flare | | Part Number | A31999-25 | | Product Dimensions | 2 x 2 x 2.5 inches | | Size | 0.25 Inch | | Specification Met | sae | | UPC | 684520319998 | ## Product Details - **Brand:** BBK - **Exterior Finish:** Brass, Stainless Steel - **Global Trade Identification Number:** 00684520319998 - **Inlet Connection Type:** Flare - **Item dimensions L x W x H:** 2 x 2 x 2.5 inches - **Material:** Brass - **Maximum Operating Pressure:** 800 Pound per Square Inch - **Number of Ports:** 3 - **Outlet Connection Type:** Flare - **Specification Met:** sae ## Images ![JB Industries A31999 Replacement Valve Core, 1/4" - Image 1](https://m.media-amazon.com/images/I/61QUbDxctPL.jpg) ## Frequently Bought Together - JB Industries A31999 Replacement Valve Core, 1/4" - Refrigeration Technologies RT201B NYLOG-GASKET/THREAD SEALANT*## - Silver Brazing Rod 15% BCuP-5 20 Flat Bar Welding Silver Phos Copper Sticks JAgP-15 Silver Phos Soldering Rods 0.050"x1/8"x14" for Air-conditioners, Refrigerators and Freezers Copper hvac --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/189392869-jb-industries-a31999-replacement-valve-core-1-4](https://www.desertcart.tn/products/189392869-jb-industries-a31999-replacement-valve-core-1-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-06*
