Built for working on WE, VFC, Marui, KSC, KWA, Northeast, Viper, EB, GHK and GMP gas guns.\n\u003c\/div\u003e\n\u003cp\u003eReplacing valves on a gas blowback is one of those jobs where the wrong tool ruins the part. Most output and fill valves use a slotted head that's easy to round off with a flat-blade screwdriver, and every brand has slightly different valve geometry. GPT's solution is a single handle with five interchangeable valve heads covering the most common gas gun manufacturers, plus a One-Touch Quick-Change socket that also accepts any standard 6.35mm (1\/4\") bit for general workshop use.\u003c\/p\u003e\n\u003cp\u003eThe handle itself is forged from 6061-T6 aluminium with an anodised finish — solid weight in the hand, knurled tactical grip pattern modelled on the MK II hand grenade silhouette so it doesn't slip even with oily fingers. The valve heads are 1144 medium carbon steel, heat-treated to 47 HRC and finished with a non-electroplated physical coating process. That coating matters: traditional electroplating contains heavy metals and solvents, and it can flake off into the gas gun internals you're trying to fix. The PVD-style coating GPT uses is both more durable and won't contaminate your work.\u003c\/p\u003e\n\u003cp\u003eKit fits in a hard storage case with a lockable lid so the heads don't escape in transit. Comprehensive cross-brand compatibility list below — these cover most of the major brands, though many other models work too since manufacturers have started mixing valve types across their ranges.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n  \u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n    \u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n    \u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHandle\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eForged 6061-T6 aluminium, anodised finish, MK II grenade-style grip\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eValve Heads\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e1144 medium carbon steel, 47 HRC heat-treated\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCoating Process\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eNon-electroplated, heavy-metal-free, solvent-free\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eQuick-Change System\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOne-Touch socket for valve heads and 6.35mm standard bits\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSet Contents\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e1× grenade handle, 5× valve heads, 1× front sight adjustment tool, 10× 6.35mm bits\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eStorage\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHard case with locking lid\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGPT-G-01S head\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCompatible with WE, Marui, KSC, WA\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGPT-G-01L head\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCompatible with VFC, Northeast, Viper, EB, GMP\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGPT-G-03 head\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCompatible with WE, VFC, KSC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGPT-G-04 head\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eLarge-type outlet valve — Viper, EB, GHK\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGPT-G-05 head\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFront sight adjustment tool — VFC, WE, Viper\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGPT-G-06 head\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCompatible with WA\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#1B3A6B;color:#fff;padding:12px 16px;border-radius:6px;margin:18px 0 0;font-size:13px;\"\u003e\n\u003cstrong style=\"color:#fff;\"\u003e💡 Titan Forge Airsoft tip:\u003c\/strong\u003e Working on a gas blowback you're not sure about? Match the valve head to the manufacturer first — most modern gas guns now mix valve patterns between models, so the compatibility list is a starting point rather than a strict rule. If a head doesn't seat cleanly, stop before you damage the valve.\n\u003c\/div\u003e","brand":"Gun Power Tools","offers":[{"title":"Green","offer_id":55559217774968,"sku":"13186876","price":54.95,"currency_code":"GBP","in_stock":true},{"title":"Sand","offer_id":55559217807736,"sku":"46583054","price":54.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/8097\/3450\/files\/GPT17-PieceGrenade-StyleValveToolKit-1.png?v=1778778414","url":"https:\/\/www.titanforgeairsoft.com\/products\/gpt-17-piece-grenade-style-valve-tool-kit","provider":"Titan Forge Airsoft","version":"1.0","type":"link"}
